Theodore Roosevelt

https://www.nps.gov/thro/index.htm https://en.wikipedia.org/wiki/Theodore_Roosevelt_National_Park Theodore Roosevelt National Park lies in western North Dakota, where the Great Plains meet the rugged Badlands. A habitat for bison, elk and prairie dogs, the sprawling park has 3 sections linked by the Little Missouri River. The park is known for the South Unit’s colorful Painted Canyon and the Maltese Cross Cabin, where President Roosevelt once lived. The Scenic Loop Drive winds past several overlooks and trails. When Theodore Roosevelt came to Dakota Territory to hunt bison in 1883, he was a skinny, young, spectacled dude from New York. He could not have imagined how his adventure in this remote and unfamiliar place would forever alter the course of the nation. The rugged landscape and strenuous life that TR experienced here would help shape a conservation policy that we still benefit from today. Theodore Roosevelt National Park is located in the Badlands of western North Dakota. There are three units to the park. The South Unit entrance is in the town of Medora, ND off of Interstate 94 exits 24 and 27. The North Unit entrance is on Highway 85 approximately 14 miles south of Watford City, ND. The remote Elkhorn Ranch Unit sits roughly in the middle of the North and South Units and is accessed via gravel roads. Consult park staff for directions to the Elkhorn Ranch Unit. North Unit Visitor Center A small visitor center is located at the park entrance for visitors to the North Unit. Speak with a ranger, receive assistance with any trip planning needs, obtain a backcountry permit, purchase a souvenir at the bookstore, or watch the park film, Refuge of the American Spirit. Restrooms are available at this location. The North Unit entrance is on U.S. Highway 85, approximately 14 miles south of Watford City, ND and 50 miles north of Belfield, ND. The distance by road from Medora to the North Unit is approximately 70 miles. I-94 travelers can access U.S. Highway 85 at Exit 42 in Belfield, ND. Painted Canyon Visitor Center Features: Panoramic views, wildlife viewing, hiking trails, staffed information desk, exhibits and displays, gift shop, picnic shelters, drinking fountain, vending machines, public telephone, and restrooms are wheelchair accessible. Take exit 32 from Interstate 94. The rest stop off of the highway includes two buildings. One is a visitor center and one includes restrooms, as well as a scenic overlook. South Unit Visitor Center Rangers staff the desk, assist visitors with trip planning, and issue backcountry permits. Theodore Roosevelt's Maltese Cross Cabin, located just outside, is open for self-guided tours year-round. Ranger-led cabin tours are offered in the summer. The park film, Refuge of the American Spirit, shows in the theater. A bookstore sells books, postcards, and more. A museum houses artifacts from Theodore Roosevelt's presidency and time in the badlands.

[Site Under Development] badlands overlook Plant Community Monitoring at Theodore Roosevelt National Park Theodore Roosevelt National Park is composed of three discrete units, each of which is a patchwork of mixed-grass prairie, clay buttes, bottomland forest, and open shrublands. The three park units are connected by the Little Missouri River. The park contains a great diversity of plants, but an increase in exotic plants could change this. We monitor plant communities here to better understand the current health of park ecosystems and to detect park-wide trends in vegetation.

Theodore Roosevelt National Park Successfully Conducts Prescribed Fire After Years of Planning In May 2014, staff of Theodore Roosevelt NP completed the Beef Corral Wash prescribed fire in Billings County. Goals included reducing fuels, stimulating new growth, altering grazing patterns of bison and elk, reducing Rocky Mountain juniper encroachment, encouraging fire-dependent plant growth, and restoring fire to a fire-dependent ecosystem that has not seen documented fire in >100 years. The fire supported a main NPS goal to restore and maintain resilient landscapes. Smoke rises in multiple places from badlands. Wildland Fire in Ponderosa Pine: Western United States This forest community generally exists in areas with annual rainfall of 25 inches or less. Extensive pure stands of this forest type are found in the southwestern U.S., central Washington and Oregon, southern Idaho and the Black Hills of South Dakota. Recently burned ponderosa pine forest.

National Park Service U.S. Department of the Interior Theodore Roosevelt National Park Coal Vein A Guided Nature Trail Hel p res us sav our e Plea ces the se retu ! rn bo xw hen this bro ch you Wa fnis ure to nt h hi See a cop y? D king bac kp . age ownlo ad for it! det ails . Be aware of the following: Cliff Edges Stairs Rattlesnakes Wildlife Poison Ivy Beautiful layers of rock tell a story of the 60-million-year geologic history of the badlands. From ancient swamps to recent coal fres, this landscape is constantly changing. Learn about badlands geology by following the numbered trail posts. Stay to the left to follow the posts in numerical order. 1. Layers Each layer of rock has its own origin story, told by its color. Brick-red Clinker forms when coal veins catch fre and bake the rock above, changing it into this much harder, red rock. Black Coal is the remains of ancient plants and animals that lived in Evergladeslike swamps. Brown and Tan Sandstone, siltstone, and mudstone are sediments washed down from the Rocky Mountains. Blue-grey Bentonite clay is made of ash from distant volcanoes. 2. Collapse In this area there was a 12-foot-thick coal vein deep underground. In 1951 it caught fre and burned for 26 years. As it burned away, the rocks above were left unsupported and the surface collapsed, forming the depression you are about to enter. Before the fre, the land was level with the top of the stairs. 3. Bentonite Notice the sediment on either side of the trail. Fifty-fve million years ago, volcanoes in the Rockies spewed out ash that blew east. At that time, this area was a vast, tropical swamp. The ash settled in wet areas and became bentonite clay. Bentonite looks like popcorn when dry (below), but becomes sticky, slick mud when wet. It can absorb up to fve times its weight in water. Known as the mineral of one thousand uses, it is used to seal landflls and ponds, to make cat litter, and much more. Stay to the left to continue on the guided nature trail. Take the right on the cutoff trail to avoid a section of trail with very steep stairs. You will rejoin the guided nature trail near post #11. 4. Caprocks Rocks in the badlands are generally soft and easily eroded by rain and streams. Some are harder than others, and become caprocks. A caprock acts like a helmet, shielding softer rock underneath. When the rocks underneath fnally erode away, large pieces of caprock break of and fall. The large pieces of sandstone behind you were once caprocks at the top of the hill. Left: An example of a caprock found elsewhere in the park. 5. Dry Climate The dry climate of western North Dakota keeps the badlands from eroding away more quickly — if rain were more common, the soft rocks would have washed away long ago. The lack of moisture allows only the hardiest plants to survive. The trees here are Rocky Mountain juniper. They, and all the other shrubs, grasses, and wildfowers you fnd here, are adapted to survive in this land of extreme temperatures and little moisture. 6. Seasonal Pool Low spots like this one formed when the ground collapsed during the coal vein fre. They fll with water in the wet springtime and after summer rains. These seasonal ponds are important 7. Burn Out Just ahead and to the right is where the coal vein fre burned out after 26 years (1951-1977). Visitors could see smoke, glowing coals, and sometimes fames. They even roasted marshmallows over the fre! Right: This photograph was taken in the 1970s as the burning coal fre crept toward its end. Caution! Steep cliff edges ahead. habitats for western chorus frogs which must lay their eggs in standing water. Listen for the chirping of the male chorus frogs near seasonal pools from April to June. 8. Hills Overlook The trail goes to the right. To your left is an overlook. Be careful; the edge drops of sharply. From the overlook, you can see how the terrain afects plant life. The slopes you see face north. They receive very little direct sunlight which helps retain moisture, allowing juniper to thrive. South-facing slopes receive a lot of direct sunlight. They are very dry and support only hardy grasses and a few drought-tolerant shrubs. 9. Clinker Feel the red rock next to the post. It is locally called scoria, but its true name is clinker. Clinker is created when a burning coal seam bakes the rock layer above it. Baking rock is like putting clay into a kiln to make pottery — the rock hardens as it bakes. Because clinker is one of the hardest rocks in the badlands, it functions as a caprock atop many buttes. 10. Seasonal Stream Just ahead, stairs lead to the valley of a seasonal stream. As you descend, notice the cool, moist air against your skin. Because it is protected from the sun, this area stays moist and cool. Note the plants you see here and compare them to the plants you have encountered in open grassland. What are the diferences? Continue straight ahead to follow the guided nature trail. 11. Ignitio

It is dry, maze-like, and rugged. Survival can be tough. Even so, many plants and animals do survive and even thrive here. Learn more as you follow the numbered trail posts. 1. Look deeper As you hike this trail, look closely. The juniper trees surrounding you now are hard to miss. Also notice the many other plants, including chokecherry, crisply scented silver sagebrush, and many grasses and small fowers. Animals eat most of these plants and Silver sagebrush ( Artemisia cana) Choke cherry (Prunus virginiana) American Indians have long used them for food or medicine. Some plants are toxic. In order to survive, people and animals had to learn which plants could help or harm them. Prairie wild rose (Rosa arkansana) Purple conefower (Echinacea angustifolia) 2. Mako shika Imagine traveling across the Great Plains in a covered wagon and coming upon this scene. The name badlands is understandable. Next, imagine yourself as a hunter on foot—butte tops become good lookouts and valleys become good places to travel undetected. Now imagine yourself as prey, using the lookouts and hiding places to evade predators. Once you get to know the badlands, you can use the rugged landscape to your advantage. Continue straight ahead to follow the guided nature trail. 3. Grasslands Grasslands look simple at frst glance, but upon closer inspection are complex. Hundreds of species of plants live in the park, most of them grasses and wildfowers. Grasslands support grazers, animals that eat mostly grass, such as bison. In fact, grasslands depend on grazers. Grazers fertilize the soil with their manure. Their pointed hooves pierce the soil allowing rainwater to fnd its way into the ground. By grazing selectively, they help many plant species thrive. 4. Shrubs Shrubs, like the silver sagebrush in front of you, provide cover for small mammals and birds and are also food for browsers (animals that eat shrubs such as deer, elk, and pronghorn.) Silver bufaloberry (Shepherdia argentea) Browsers and fres keep shrubs from overtaking the grasslands. Without them, tree and shrub cover increases, shading out smaller plants and reducing the prairie’s diversity. Rubber rabbitbrush (Chrysothamnus nauseosus) Golden currant (Ribes aureum) Continue straight ahead to follow the trail posts in numerical order. 5. Expressway Travel through the badlands is much faster since the construction of Interstate 94 in the 1960s. Increased travel to and through the badlands Caution! Steep cliff edges ahead means more chances of introducing plants and animals that aren’t originally from this area. Some introduced species are damaging; others are not. 6. New Neighbors Not all of the plant species you see were here 200 years ago. Those that were here before European settlement are called native species. The prairie depends on native species to play their part in the environment–as food or shelter for animals, or as protection and nutrients for soil. Plants that have been introduced are called non-native species. Many non-native species blend into the environment and do not pose a threat; others become a problem. These problem species are called invasive species. 7. Invaders Invasive plants, such as Canada thistle, often spread quickly and take over large areas, crowding out native species. Some invasive plants, like leafy spurge, slow the growth of nearby plants by releasing toxic chemicals from their roots. Many invasive plants Canada thistle (Cirsium arvense) cannot be eaten by native wildlife. Their spread reduces the amount of food available for grazers. Theodore Roosevelt National Park is actively fghting to keep invasive species from overtaking the native prairie. Leafy spurge (Euphorbia esula)) Smooth brome (Bromus inermis) Continue straight along the ridge to the next post. 8. Variety As you look out across the landscape, notice its diversity: some areas have trees; some are grassy; and some are almost bare. This is the infuence of terrain on plant life. Do you see the pattern? Trees grow where they can get enough water, usually along streams or northern sides of hills where the sun doesn’t dry up moisture as quickly. Grasses are adapted to dry areas like the tops and southern sides of hills. 9. Cooling Down You are entering the north slope of the ridge you’ve been walking along. Notice there are fewer grasses and more trees and shrubs. Grasses t
