Florissant Fossil Beds
National Monument - Colorado
The Florissant Fossil Beds National Monument is located in Teller County, Colorado. The location is famous for the abundant and exceptionally preserved insect and plant fossils that are found in the mudstones and shales of the Florissant Formation. Based on argon radiometric dating, the formation is Eocene (approximately 34 million years old) in age and has been interpreted as a lake environment. The fossils have been preserved because of the interaction of the volcanic ash from the nearby Thirtynine Mile volcanic field with diatoms in the lake, causing an diatom bloom. As the diatoms fell to the bottom of the lake, any plants or animals that had recently died were preserved by the diatom falls. Fine layers of clays and muds interspersed with layers of ash form "paper shales" holding beautifully-preserved fossils.

Beneath a grassy mountain valley in central Colorado lies one of the richest and most diverse fossil deposits in the world. Petrified redwood stumps up to 14 feet wide and thousands of detailed fossils of insects and plants reveal the story of a very different, prehistoric Colorado.
Visitors traveling north/south on I-25: Exit at US 24 West, travel 35 miles to town of Florissant, then follow signs two miles south on Teller County Road 1 to the Visitor Center. Visitors traveling from town of Cripple Creek: Follow Teller County Road 1 north for 16 miles.
Florissant Fossil Beds Visitor Center
The Visitor Center is where you should start your visit to Florissant Fossil Beds. At the Visitor Center you can show your pass, if you have one, and/or get passes. There is also a museum full of fossil exhibits, a theater to see the park film, and a bookstore. The Visitor Center also has bathrooms and a water fountain.

National Park Getaway: Florissant Fossil Beds National Monument
Set aside as a national monument in 1969, this lesser-known national park protects one of the richest fossil deposits in the world. Over the past 140 years, paleontologists have also found fossils of plants, mammals, fish, birds, snails, and mollusks. That level of diversity of fossil insects at any one locality is extraordinarily rare in the world.

Checking Florissant's Vital Signs
In 2007, the Rocky Mountain Inventory and Monitoring Network—a small team of NPS scientists—began monitoring natural resources, called “vital signs,” in Florissant Fossil Beds and nearby park units. Vital signs indicate park health and serve as red flags if conditions deteriorate, supporting park managers’ efforts to make science-based management decisions. Learn about the NPS Inventory and Monitoring Program and its work in Florissant Fossil Beds National Monument.

Wildland Fire in Douglas Fir: Western United States
Douglas fir is widely distributed throughout the western United States, as well as southern British Columbia and northern Mexico. Douglas fir is able to survive without fire, its abundantly-produced seeds are lightweight and winged, allowing the wind to carry them to new locations where seedlings can be established.

Draw Your Own Big Stump Face Challenge
Florissant Fossil Beds protects some of the largest petrified tree stumps in the world by diameter. During the 1800s, people tried to saw the park's famous Big Stump into pieces. If you look close enough, you can make out a grumpy face on the Big Stump. Use templates to decorate Big Stump as your own artistic masterpiece without causing damage to these protected resources.

Series: Geologic Time Periods in the 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.

Series: Badlands Geology and Paleontology
Badlands National Park is well-known for its geology and paleontology. Fossils found in the park range from 75- to 28-million years old and many are in excellent condition. The flat-lying layers of the park's formation represent classic sedimentary rock layers.

Series: Photogrammetry Applications and Examples
Photogrammetry is the science and art of using photographs to extract three-dimensional information from a series of well-placed images. Paired with either a standard ruler or GPS locations of camera positions provides the scale in completed models. This Series provides examples of photogrammetry projects for a variety of resources in National Parks.

Women & Paleontology in the Badlands
Although Badlands National Park is proud to employ many female paleontologists today, this scientific field was not always accepting of women. In this article, learn about how women's roles in paleontology have changed over years of Badlands research.

Volcanic Processes—Lahars
Lahars are volcanic mudflows and are among the most destructive of volcanic phenomena. Lahars present significant geohazards since they can travel great distances down river valleys and impact population centers away from the immediate area of a volcano.

Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks
Across the US, changes in water availability are altering which plants grow where. 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.

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.
