https://www.nps.gov/dena/index.htm https://en.wikipedia.org/wiki/Denali_National_Park_and_Preserve Denali National Park and Preserve encompasses 6 million acres of Alaska’s interior wilderness. Its centerpiece is 20,310-ft.-high Denali (fka Mount McKinley), North America’s tallest peak. With terrain of tundra, spruce forest and glaciers, the park is home to wildlife including grizzly bears, wolves, moose, caribou and Dall sheep. Popular activities in summer include biking, backpacking, hiking and mountaineering. Denali is six million acres of wild land, bisected by one ribbon of road. Travelers along it see the relatively low-elevation taiga forest give way to high alpine tundra and snowy mountains, culminating in North America's tallest peak, 20,310' Denali. Wild animals large and small roam un-fenced lands, living as they have for ages. Solitude, tranquility and wilderness await. You can drive to Denali from Anchorage or Fairbanks, along Highway 3, which is known as the "George Parks Highway." Fairbanks is about 2 hours north, while Anchorage is 5 hours south of the Denali entrance. You can also reach Denali from either city via the Alaska Railroad, which is operated by the State of Alaska. A small private airstrip is also available near the park entrance for individuals wishing to fly their own small craft to the park. Denali Bus Depot This summer facility is operated by our concessionaire rather than by the National Park Service. It is the primary place to buy bus tickets, arrange for stays in park campgrounds, or to check in for an existing reservation. Coffee and grab-and-go food is also available for purchase. Only credit cards are accepted here. Denali Visitor Center Open in summer only, this is the main visitor center near the park entrance. During the summer, you can explore exhibits, watch the park film, pay the park entrance fee, and talk with a ranger. In fall, winter and spring, the Murie Science and Learning Center (MSLC) acts as the park's Winter Visitor Center. Upon arriving in Denali, travel 1.5 miles down the road until you see signs for the Denali Visitor Center. Eielson Visitor Center The Eielson Visitor Center is located at Mile 66 of the Denali Park Road. Due to the ongoing Pretty Rocks landslide and the closure of the park road at Mile 42, Eielson is currently closed. Eielson is located at Mile 66 of the Denali Park Road, and as such can only be accessed by visitors on certain buses, or visitors who are hiking / biking the road. Indoor Picnic Area A heated building, called the Indoor Picnic Area, is located next door to the Murie Science and Learning Center, which is across the street from the Denali Visitor Center. Restrooms and a water bottle filling station are available. Food service is not provided, so bring your own food to eat. Turn off Highway 3 onto the Denali Park Road and drive 1.4 miles til you see signs for the Murie Science & Learning Center. Park at the Murie Center, and walk past it to the Indoor Picnic Area. Murie Science and Learning Center The Murie Science and Learning Center (MSLC) is located at Mile 1.3 of the Denali Park Road at the entrance of Denali National Park and Preserve. In summer (June 1 – late August), the MSLC hosts educational science activities during daily open hours from 1–3 pm. In winter (mid October – mid May), the MSLC serves as Denali’s Winter Visitor Center. After entering the park, travel 1.4 miles and look for signs to the Murie Science and Learning Center. Walter Harper Talkeetna Ranger Station Located in the town of Talkeetna, about 100 miles south of the entrance to Denali National Park and Preserve, this ranger station serves as the center of mountaineering operations. Climbers wishing to attempt Denali or other peaks in the Alaska Range stop here first, for an orientation to the mountain and to acquire their climbing permit. This ranger station also offers some visitor services, particularly in summer. It is open year-round. The Talkeetna Spur Road is at Mile 100 on Highway 3. Drive down the Talkeetna Spur Road its full 15 mile length to the town of Talkeetna and look for the visitor center on B street. Igloo Creek Igloo Creek Campground will be closed in 2023. The campground is at mile 35 on the Park Road. It offers 7 sites, making it the smallest in Denali (along with Sanctuary River Campground, which also has 7 sites). Igloo is tent-only—you will not find any RVs or other vehicles in this campground. It is accessible only by camper bus. The bus stop is a short walk from the campsites (less than 50 yards). Nightly Fee 21.75 This is the cost to stay per night at Igloo Creek Campground. You may stay up to 14 total nights in a given summer. Three tents and up to eight people may use a single site. Igloo Welcoming Committee two brown bears scratching at a large wooden sign that reads "Igloo Creek Campground" While many visitors do not see bears at Igloo Campground, remember that you are camping in bear country. Camping at Igloo two people sitting in chairs outside of their tent in a forest Igloo Campground is in the middle of Igloo Forest, which is mainly made up of spruce trees. Igloo Creek Campground person sitting near an orange tent Campsites in Igloo Creek have some brush screening between sites. Filling water at Igloo Creek a woman filtering water into a plastic bottle from a shallow creek Igloo Creek has no well or water tap. Water must be gathered from the nearby creek, so bring a filter. Igloo Creek Food Locker a woman placing food into a large metal locker Food lockers at Igloo Creek ensure that wildlife cannot steal your food. Keep all scented items (e.g., deodorant, toothpaste) in the locker, not just your food. Relaxing at Igloo Creek Campground A grizzly on its hind legs leaning on a large wooden sign that reads "Igloo Creek Campground" Keep in mind that bears can be found nearly anywhere in Denali. Keep your food and other scented items stored properly in the campground facilities provided! Covered Shelter picnic tables covered by a wall-less, roofed enclosure in a forest A covered eating area is available at Igloo Creek Campground Restrooms at Igloo wooden building with two doors in a forest Igloo has two pit toilets for campers. Riley Creek Riley Creek is a fairly wooded campground, with some screening between sites whenever possible. Most of the campground sites are open to either tent campers or vehicles / RVs. The proximity of Highway 3 means there is occasional traffic noise, but also means campers have all the conveniences and amenities of the park entrance area, and businesses outside the park, close at hand. Trails leading from the campground connect to the Denali Visitor Center, which is the central hub of trails in the entrance area. Winter - Free 0.00 Camping is free in winter. The winter season begins fifteen days after Labor Day each September, and lasts through early May each year. Summer - Large RV Sites 45.00 Some sites can accommodate RVs up to 40' in length. These sites cost a bit more per night than the smaller sites, which can accommodate vehicles no larger than 30' long. Summer - Small RV Sites 35.25 These sites can accommodate vehicles up to 30' long. If you have a truck and trailer, the total combined length must be less than 30' to use one of these sites. Summer - Tent Only 21.75 The tent-only sites at Riley are first-come, first-served, meaning they cannot be purchased before you physically arrive in the park. These sites do not have parking at them, you must park elsewhere and walk into these sites. Group Site (Tent-only) 49.00 A group site at Riley Creek Campground has space for up to 12 tents. The group site can only be used by non-commercial groups (including groups like Girl Scouts and Boy Scouts of America, etc). There are no fire rings at the site, and tents must be set up on the established tent pads. Riley Creek Campfire a man lighting a campfire, and a woman pulling gear out of a car Up to two vehicles may park at a Riley Creek Campsite, as long as the total vehicle length doesn't exceed the campsite's max (either 30' or 40') Riley Creek Campground an empty campsite in a spruce forest A typical site in Riley Creek Campground. Riley Creek Tent Site two people spreading a tent out on a gravel pad Riley Creek Campground has some tent-only sites, though most sites are open to RVs. RV sites are split into <30' and <40'. Riley Creek Campground three women at a picnic table near a tent Riley Creek is open to RVs and tent campers Sanctuary River Open in summer only (May 20 to mid-September). Sanctuary River is a heavily wooded campground, with screening between most sites. The immediate area is brushy, but nearby mountains offer chances to hike directly from the campground and gain elevation, with views of Denali to the south possible on clear days, after some strenuous up-hill hiking. Sanctuary is tent-only—you will not find any RVs or other vehicles in this campground. It is accessible only by camper bus. Nightly Fee 21.75 This is the cost for one campsite for one night. Three tents and up to eight people may use a single site. You may stay up to 14 total nights in a given summer. Sanctuary River a wide, shallow river flowing through a brushy forest The area around Sanctuary River turns shades of yellow, orange and red in fall (mid-August) Savage River Open in summer only (May 20 to mid-September). Savage River campground is located at Mile 13 on the Denali Park Road. It sits in a spruce forest, with moderate screening between sites. On clear days, Denali can be seen from a short walk below the campground. Large RV Sites 45.00 Nightly fee for a site that can accommodate an RV between 30' and 40' long. Small RV / Tent Sites 35.25 Nightly cost for a site that can accommodate an RV that is less than 30' long, as well as any other vehicle or even tent campers without vehicles. Group Site 49.00 Standard sites in Savage can accommodate up to 8 people (in up to 3 tents). Larger groups may rent a group site by calling 866.761.6629. Savage River a braided river flowing through a brushy landscape A short walk southwest of the campground is Savage River, which flows northward from the Alaska Range. Savage River Campground dirt road in a forest with hills in the distance South of the campground, the spruce forest ends and views of the Alaska Range become possible South of Savage River a landscape of spruce trees, rolling hills and distant mountains The view to the south of Savage River Campground, looking toward the Alaska Range Savage River Canyon two marmots sitting on rocks Savage River Canyon is about a mile away from Savage River Campground, and can be a great spot to look for wildlife. Evening Ranger Talk at Savage Campground a crowd of people sitting on wood benches in a forest listen to a park ranger speaking Evening campground talks happen most nights at Savage River Campground during the summer Savage River Campground A wood sign reading Savage River Campground The entrance to Savage River Campground Teklanika River Open in summer only (May 20 to mid-September). Though nearly all private vehicles must turn around at mile 15, Savage River, Tek campers are an exception to that rule. If you wish, you may drive your vehicle / RV to Tek. The trade-off is that you must make, at minimum, a three-night stay, and your vehicle must stay in your campsite for the duration of your stay, while you use transit buses to sightsee. Tent campers using the park bus system to reach Tek are not subject to the 3-night minimum stay. Nightly Fee 37.50 This is the cost, per night, for a campsite at Teklanika Campground. A single site can contain up to eight people and up to three tents. This is the fee for all campers, regardless of whether you have just a tent, or an RV or other vehicle. Tek Pass 32.75 Strongly recommended. The Tek Pass is a bus ticket that lets you use transit buses throughout your stay at Tek. The pass acts like a normal transit ticket for your first trip (i.e., on a specific bus you choose); on subsequent trips, you can board any transit bus for a day-trip farther into the park. You cannot drive your vehicle to/from the campground except at the start and end of your stay, so this is the only way to sightsee while camping at Tek. (Note: This pass is free for kids 15 and younger.) Teklanika Campground two people outside of an RV, one relaxing in a camp chair by a fire while another prepares a meal You can camp at Tek River with an RV (less than 40'), a car, or just a tent. Sites have a grate for cooking over a fire, but bring your own firewood and don't forget to burn or scrape off any food residue from the cooking surface. Teklanika River a wide, braided river flowing past forests and mountains A short walk west of Teklanika (Tek) Campground is Tek River, which flows northward from the Alaska Range. Clean Camping several people in camp chairs around a fire, under a tarp hung from trees Remember to keep a clean camp. Food should only be outside when you're actively preparing and eating a meal. Otherwise, use the food lockers or your hard-sided vehicle to keep your food safe from wildlife. Campers two women sitting near a campfire with a truck and cab-over-camper behind them Teklanika River is the second largest campground in Denali, but is one of the most remote. No electrical or water hookups are available, though bathrooms and potable water taps are available in the campground. Teklanika Amphitheater numerous wooden benches in a spruce forest The Teklanika area is wooded, though less-so than Riley Creek and Savage River Campgrounds Ranger Program at Teklanika Campground a crowd sitting on benches faces a park ranger giving a talk Ranger programs occur most evenings of the summer at Teklanika River Campground. Tent Camping at Teklanika an SUV parked in a forest with a tent behind it Campers may use RVs or tents at Teklanika in most years. Occasional bear incidents may cause restrictions on tent-camping, but such events are rare (and unpredictable). Teklanika Restrooms a small wooden building with two doors Restrooms at Teklanika Tek Campground people sitting by an outdoor fire near an RV, in a sparse forest Campers at Teklanika Wonder Lake Wonder Lake Campground is closed through 2024. Wonder Lake Campground is at mile 85 on the Denali Park Road. It offers 28 tent-only sites. It is the closest campground to Denali. Though separated by nearly 26 miles, the sheer size of the mountain makes it loom impressively over Wonder Lake Campground. Cloudy skies can obscure views, and mosquitoes can be fierce, but Wonder Lake on a clear day offers views that will last a lifetime. Bear-proof food lockers are available throughout the campground. Reservation Fee 8.00 This is a one-time reservation fee. It applies whether you stay one night or fourteen (or a number in between) at this campground. Park passes do not waive this fee, as it is charged by our concessionaire. Nightly Fee 16.00 This is the cost, per night, to stay at Wonder Lake Campground. Please note that your total cost for the campground is $6 (the one-time reservation fee) + the total nightly cost of your stay. Up to four people may use a single site. Sitting on a Dock in the Lake a young woman sitting on a dock sticking out into a lake Wonder Lake is too chilly for most swimmers, but can make for a very scenic spot.

Abandoned Mine Lands in Alaska National Parks—An Overview From the thousands of mining claims that existed at when Congress created most national parks in Alaska, around 750 still remain. These are mainly abandoned sites and features, in various stages of disrepair and failure. Since 1981, the NPS has worked to quantify the number and type of hazards posed by these sites and has pursued a variety of solutions to mitigate the issues, such as visitor safety hazards, presented by relic mining features. dilapidated wood building in a mountainous setting Subsistence The study of subsistence resources in parks has been a mix of long-term work and projects instigated by issues facing the Federal Subsistence Board.

Painting of a wolf walking on a gravel along a braided river Kantishna Gold! Gold mining in the American West at the turn of the 20th century will forever be remembered for its sudden and feverish stampedes. In the 1890s, after thousands rushed to Canada’s Klondike goldfields, many miners headed west to try their luck in Alaska. Stampeding became a way of life for many frontier adventurers, and when Alaska’s boomtowns became too crowded or the pay-dirt too scarce, these wanderers followed rumors of gold into Denali's Kantishna region. Land Ownership in National Park System Units in Alaska and Possibilities for Mining and Other Developments There are over 54 million acres of National Park System units in Alaska, which is 65 percent of the entire National Park System. Although most of those lands are in federal ownership and are managed by the NPS, there are over two million acres of non-federally owned lands within those units. These non-federal lands are in private, state, borough, or municipal ownership. The existence of these lands creates the possibility of mining and other developments within the boundaries rustic buildings near a creek, hills and mountains in the distance Landsat 8 Helps Map Fires during Long, Busy Alaska Fire Season The Castle Rocks fire occurred about 100 miles west of Denali park headquarters and 160 miles southwest of Fairbanks.

Tracking Human Waste on Denali Science Summary (2011) - Poop happens. Between 1951 and 2012, climbers have deposited at least 152,000 lbs (~70 metric tons) of human waste in the Kahiltna Glacier. Discover how scientists measure the amount of waste -- and its downstream effects, like e coli -- and how Denali strives to mitigate the issue. three people crouched together on a glacier Back in Time: A Watch and the Story of an Early McKinley Station Resident In summer of 2017, Denali archaeologists working on a Section 106 compliance survey close to the historic McKinley Park Station site discovered a piece of history: a two-inch pocket watch with the inscription “WM ALLMAN MCPARK ALASKA.” Who was WM ALLMAN? man kneeling by a creek National Park Getaway: Denali National Park & Preserve Most visitors only experience the park during summer, and they are very curious about Denali in winter. They've heard it's cold and that the days are short. While both are true, either experience in Denali will be unforgettable. Caribou in a grass field Origins of Soundscape Monitoring in Denali Soundscapes, the combined sounds from natural and non-natural sources, are recognized as an important resource in national parks. In the year 2000, park managers recognized that the natural soundscape of Denali was increasingly affected by non-natural sounds. Because preserving the natural soundscape also helps preserve the associated wilderness values and visitor experiences, a soundscape program was initiated. two microphones in a tree-less meadow near steep, snowy mountains Bottom-Up Ecosystem Drivers Read the abstracts and get the links to two published papers that discuss ecosystem drivers and tropic relationships.

The Fate of Permafrost At present, permafrost is continuous in Arctic parks and discontinuous in Denali and Wrangell St.-Elias national parks and preserves. We expect the distribution of permafrost will still be continuous in Arctic parks by the 2050s; however, it is very likely that the distribution of permafrost in Denali and Wrangell-St. Elias will become sporadic by then. a person standing next to an eroded hillside Economics of Wilderness: Contribution of Alaska Parks and Wilderness to the Alaska Economy Looking ahead, it is clear that Alaska’s wilderness ecosystems will become increasingly valuable assets in a crowded urban world. If Alaska’s wild lands, wildlife, and ecological integrity are cared for with respect, the contribution of wilderness and conservation lands to the Alaska economy and to people everywhere will be significant, positive, increasing, and enduring. a large cruise ship on the ocean with snowy mountains in the distance CRASH! The Alaskan Bush Hits Climate Change... or Does it?

Denali has relatively few non-native plant species (28) compared to parks in the Lower 48 states. By aggressively eradicating invasives now, while their numbers are manageable, we can avoid exotic species compounding the ecological challenges posed by factors like climate change. people pulling up yellow flowers by a roadside Wolf Dispersal in Alaskan Parks Wildlife biologists have long known that wolves occasionally travel enormous distances in search of new mates and ranges. However, the advent of GPS-based wildlife tracking has allowed researchers to follow in the very footsteps of wolves as they travel across vast and wild landscapes. Alaska National Park scientists have witnessed some surprisingly intimate and breathtaking interconnections between wolves, parks and people by using this technology over the last few years. Close up of a wolf standing and facing the camera SMART Collars Reveal the Hidden Lives of Wolves Science Summary (2017) - In recent years, fitness devices and smartphone applications have been sweeping the nation. These gadgets allow users to create their own digital journal of where they go, what they do, and how much energy they use. Now, researchers are using the same technology to discover the hidden lives of wild wolves in Denali. a wolf wearing a collar walks through the snow Monitoring Dust Palliative Use Along the Denali Park Road Annual Research Updates (2016) - To reduce road dust along the Denali park road, maintenance crews apply a solution of calcium chloride to the road surface, and now monitor the possible effects soil, water, and vegetation may experience. a dump truck kicks up dust along the Denali park road Native Seed Collection and Invasive Plant Eradication Annual Research Updates (2016) - Native seed collection is important to help make revegetation projects possible.

Alaska Park Science (2015) - Within just six weeks of fledging, some of Denali’s juvenile eagles fly over 4,000 miles to spend the winter in central Mexico. Here they are in the company of other migratory golden eagles from interior and northern Alaska and northwest Canada, flying back to Alaska in the spring. Changing climate, and changing habitat over those thousands of miles, presents significant challenges to eagles' survivability. a golden eagle in flight in a blue sky Major Discovery in Denali's Microwilderness Science Summary (2016) - Bees and flower flies are two important groups of pollinators in Denali. Without their help in carrying pollen between flowering plants, there would be no wildflowers on the tundra, no blueberries for grizzlies to eat, and no fireweed blazing along the park road. Researchers already knew pollinators are vital to Denali ecosystems, but until recently, the park knew little about the individual species that make up this invaluable group of animals. Close up of new species, Bombus kluanensis Patterns of arthropod diversity and activity along elevational gradients in Denali Annual Research Update (2016) - For the vast majority of Denali’s animals (aka the invertebrates), there is an incomplete picture. Researchers don’t have a good idea about which species live here or how they are distributed across habitats. To be able to track invertebrate responses to effects from climate change, it is necessary to start with a basic understanding of who lives here, now. a blue vane trap on a hillside with Denali in the background Hearing the Difference—monitoring sounds in Alaska's National Parks NPS biologist Davyd Betchkal installs a sound-monitoring station near Triple Lakes in the Denali Park wilderness.

In the process, they discovered the date of spring onset most-notably influences their populations. Among other reasons, voles are an important species because their abundance influences carnivore populations higher up the food chain. closeup of a hand, holding a vole Long-Term Air Quality Monitoring in Denali National Park Air quality monitoring in Denali has been ongoing for over three decades. With global pollution projected to increase over time, Denali’s clean air is dependent upon international as well as national efforts to limit emission increases. As a prominent wilderness tourist destination, the park may help inspire global citizens to protect clean air partly because it is an integral part of Denali’s intact ecosystem. clouds brewing over a snowy mountainside My Wilderness Essay: Bette Burt Denali - where in a matter of hours, the terrain changes as you drive inward: from tall woodland forests, to scrub land with trees no taller than 4½ - 6 feet, to tundra with nothing growing over 4½ - 6 inches! vast snow covered mountain dominating a hilly landscape My Wilderness: Joe Horiskey Mountaineer Joe Horiskey recounts one particularly memorable trip, out of over twenty expeditions on Denali, in his essay for "Your Wilderness Stories." vast snowy mountain dominating a hilly landscape My Wilderness: Donna Morefield Campbell Denali...the name stirs up a yearning.

Over half of Alaska’s antimony production from the 1940s and 1950s came from this region, and the Stampede Mine (now within Denali National Park and Preserve) is Alaska’s historically largest antimony producer. Man collects sediment from a small creek Melting Glaciers in the Kichatna Mountains Science summary (2011) - Sheer limestone cliffs and granite spires surrounding more than a dozen small mountain glaciers comprise the Kichatna Mountains tucked away in the remote southwestern corner of Denali National Park and Preserve. Most park visitors do not travel to the Kichatna Mountains, yet the results of climate change are visible there as glaciers melt and recede. The Kichatna glaciers, being relatively small, are particularly vulnerable to faster rates of melting. man standing on a glacier in the Kichatna Mountains Restoration of Mined Lands in Kantishna The early stampede of fortune seekers to the Kantishna Mining District in 1905 subsided quickly, yet mining continued intermittently there through 1985. Part of the legacy of Kantishna mining was holes in the hillsides, non-functional floodplains, and streams downcutting and eroding banks and tailing piles. Here's how the park hopes to restore the streams in Kantishna today. an excavator sits in a rocky gravel pit Soil Survey and Ecological Classification in Denali Did you know that soil will have different characteristics depending on where you are in Denali?

Visionary as it was, the Wilderness Act did not anticipate today’s human-driven, global-scale changes. The idea of preserving wild lands challenges us with the irony that such places, untouched by humans, will only continue through our will to keep them that way. A resolute human purpose is needed to maintain the decision to have areas that are free of human purpose. aerial view of wolves moving single-file through a snowy forest Using Ethics Arguments to Preserve Naturalness: A Case Study of Wildlife Harvest Practices on NPS Lands in Alaska The NPS responsibility to maintain natural wildlife populations is inherently challenging. For example, many animals migrate out of parks either seasonally or long-term. Typically, we collect and analyze data, and then publish our work. However, the answer rarely, if ever, lies solely in the data. Often the question is not even one of biology, but one of values.

During the Mesozoic, Pangaea began separating into the modern continents, and the modern Rocky Mountains rose. Dinosaurs, crocodiles, and pterosaurs ruled the land and air. As climate changed and rapid plate tectonics resulted in shallow ocean basins, sea levels rose world-wide and seas expanded across the center of North America. fossil dinosaur skull in rock face Series: Geologic Time Periods in the Paleozoic Era During the Paleozoic Era (541 to 252 million years ago), fish diversified and marine organisms were very abundant. In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era. fossil corals in a rock matrix Series: Copper River Basin Symposium - Wrangell-St Elias National Park and Preserve February 2020: With a theme of Tradition, Science, and Stewardship, the two-day symposium included keynote speakers, 26 short presentations, and a poster session.

Using Aquatic Invertebrates to Measure the Health of Stream Ecosystems: New Bioassessment Tools for Alaska’s Parklands Aquatic insects are good indicators of stream ecosystem health because they are common, reasonably well understood, easy to collect and analyze, and sensitive to the environment in which they live. We can determine the relative health of a stream by comparing what insects we find to what we would expect to find in a similar healthy stream. This straightforward approach can be used in all kinds of settings and compared across a region.

It is inviting and it is terrifying; accessible and remote. Welcoming and isolating. It is an essentially undeveloped wilderness with a road corridor through the middle that brings millions of people to its edge. It is untrammeled, yet managed. Some of the land within its boundaries is well known and studied, but much of it is full of mystery. Dog sled travel in Denali.

Across the country, there are 32 inventory and monitoring networks that measure the status and trends of all kinds of park resources. We're learning a lot after years of collecting data. Check out these articles written for kids and reviewed by kids in partnership with the international online journal Frontiers for Young Minds. A cartoon of a ranger taking the pulse of the Earth. NPS partners with Project Learning Tree for fire ecology workshop In June 2022, NPS Alaska regional fire ecologist Jennifer Barnes taught at an educator workshop at Denali National Park and Preserve hosted by Project Learning Tree (PLT). It was one of the many educator and continuing learning series opportunities that Barnes has led in Alaska throughout her career. The workshop, held at the Murie Science and Learning Center Field Camp, brought together educators from across the state to learn about the unique fire ecology in Denali National Several people stand outside in a forested area. Series: Geologic Time—Major Divisions and NPS Fossils The National Park System contains a magnificent record of geologic time because rocks from each period of the geologic time scale are preserved in park landscapes. The geologic time scale is divided into four large periods of time—the Cenozoic Era, Mesozoic Era, Paleozoic Era, and The Precambrian. photo of desert landscape with a petrified wood log on the surface Guide to the Thomas J.

Murie never worked for the National Park Service (NPS), his biological research and conservation advocacy had significant impacts on the protection and management of NPS lands, wilderness, and species. His half-brother, Adolph Murie, did work for the NPS and it was their connection that resulted in a small collection of Olaus Murie's sketches becoming part of the NPS History Collection. Sketch of the side view of a wolf The McKinley Park Hotel The 1972 fire at the McKinley Park Hotel occurred at the end of a busy summer that saw a substantial jump in visitation due to the new highway (Highway 3) linking Anchorage to Fairbanks, with Denali being one of the key attractions on the route. a building on fire Outside Science (inside parks): Picturing a Changing Climate Follow us to the backcountry of Denali National Park where a group of young scientists document changes in the landscape. A group of students backpacking in Denali National Park Assessing the Effects of Traffic on the Behavior and Viewability of Grizzly Bears A new study on grizzly bears in Denali will assess changes in bear movement and habitat use along a 30-mile segment of the Denali Park Road. The two-year closure of the western half of the park road provides an unprecedented opportunity to study the before and after effects of high traffic volume on grizzly bears. The study aims to provide park managers with a deeper understanding of how traffic patterns affect wildlife viewing opportunities, animal behavior, and habitat use.
