Fossil Butte

https://www.nps.gov/fobu/index.htm https://en.wikipedia.org/wiki/Fossil_Butte_National_Monument Fossil Butte National Monument is located 15 miles (24 km) west of Kemmerer, Wyoming, United States. It centers on an extraordinary assemblage of Eocene Epoch (56 to 34 million years ago) animal and plant fossils associated with Fossil Lake—the smallest lake of the three great lakes which were then present in what are now Wyoming, Utah, and Colorado. The other two lakes were Lake Gosiute and Lake Uinta. Fossil Butte National Monument preserves the best paleontological record of Cenozoic aquatic communities in North America and possibly the world, within the 50-million-year-old Green River Formation — the ancient lake bed. Fossils preserved — including fish, alligators, bats, turtles, dog-sized horses, insects, and many other species of plants and animals — suggest that the region was a low, subtropical, freshwater basin when the sediments accumulated, over about a 2 million-year period. Some of the world's best preserved fossils are found in the flat-topped ridges of southwestern Wyoming's cold sagebrush desert. Fossilized fishes, insects, plants, reptiles, birds, and mammals are exceptional for their abundance, variety, and detail of preservation. Most remarkable is the story they tell of ancient life in the warm, wet environment in and around a freshwater lake. By car: Travel 9 miles west of Kemmerer, Wyoming on U.S. Highway 30.

The Northern Colorado Plateau Network partners with the University of Delaware to assess breeding-bird species trends in three different habitats: low-elevation riparian, pinyon-juniper, and sage shrubland. Find out which species were increasing and declining at network parks as of 2018. Small, bright-orange bird with yellowish underfeathers. Wildland Fire in Sagebrush Sagebrush will burn when the surrounding grasses are dry. With strong winds, fire spreads rapidly with flames sometimes reaching over 30 feet high. While fire easily kills sagebrush, the other plants resprout from protected roots producing lush forage for wildlife and livestock. Close-up of sagebrush leaves What We’re Learning and Why it Matters: Long-Term Monitoring on the Northern Colorado Plateau Knowing which key natural resources are found in the national parks, and whether they're stable or changing, helps decisionmakers make sound choices. The Northern Colorado Plateau Network is building that knowledge. After more than ten years of monitoring, we've learned a lot about park ecosystems, how they're changing, and what they may look like in the days to come. Find out what we’ve learned and how it’s being used to help managers plan for the future. Man stands in a stream, looking down at a handheld gauge.

Links to products from Baseline Geologic and Soil Resources Inventories provide access to maps and reports. [Site Under Development] park landscape Cenozoic Era The Cenozoic Era (66 million years ago [MYA] through today) is the "Age of Mammals." North America’s characteristic landscapes began to develop during the Cenozoic. Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age woolly mammoths. fossils on display in a visitor center Landbird Population Trends in the Northern Colorado Plateau Network, 2020 Because birds can be sensitive to habitat change, they are good indicators of ecosystem integrity.

Monitoring From Space: Using Satellite Imagery to Measure Landscape Conditions on the Ground Scientists from the Northern Colorado Plateau Network travel thousands of miles each year to collect data on plants, soils, and water across network parks. But it would be impossible to cover every square inch of the Northern Colorado Plateau with boots on the ground. Instead, we simultaneously monitor the parks with boots in space—satellite data that provide information at a much broader scale. Satellite and Earth in space Localized Drought Impacts on Northern Colorado Plateau Landbirds Birds of the desert southwest, a climate-change hotspot, are among the most vulnerable groups in the US. To help park managers plan for those changes, scientists evaluated the influence of water deficit on landbird communities at 11 national parks in Utah and Colorado. The results will help land managers to focus conservation efforts on places where certain species are most vulnerable to projected climate changes.

These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.

Volcanic Ash, Tephra Fall, and Fallout Deposits Volcanic ash, pumice, and tephra ejected in volcanic eruptions ultimately falls back to Earth where it covers the ground. These deposits may be the thin dustings or may be many tens of feet (meters) thick near an eruptive vent. Volcanic ash and tephra can present geohazards that are present great distances from the erupting volcano. photo of a bluff with exposed fine-grained volcanic ash and pumice. Invasive Exotic Plant Monitoring at Fossil Butte National Monument Invasive exotic plants are one of the most significant threats to natural resources in the national parks today. To provide early warning of weed invasions, the Northern Colorado Plateau Network monitors target plants in park areas where they are likely to first establish: along roads, trails, and waterways. Find out what we've learned at Fossil Butte National Monument. Tall green grass with seedy tufts. 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 Making an Impact: Long-Term Monitoring of Natural Resources at Intermountain Region National Parks, 2021 Across the Intermountain Region, Inventory & Monitoring Division ecologists are helping to track the effects of climate change, provide baseline information for resource management, evaluate new technologies, and inspire the next generation of park stewards.

A Changing Bimodal Climate Zone Means Changing Vegetation in Western National Parks When the climate changes enough, the vegetation communities growing in any given place will also change. Under an expanded bimodal climate zone, some plant communities in western national parks are more likely to change than others. National Park Service ecologists and partners investigated the future conditions that may force some of this change. Having this information can help park managers decide whether to resist, direct, or accept the change. Dark storm clouds and rainbow over mountains and saguaros.
