Yosemite National Park: Since the glaciers retreated around 15,000 years ago, rock fall has been the major force of change in Yosemite Valley. Geologists work to understand this force of nature in order to protect the millions of visitors who come here each year.

Valley Forge NH Park: The geology of the Grand Parade is discussed by the park’s natural resource manager.

Glacier National Park: Geologist Chris Weiss briefly discusses the geologic history of Glacier National Park.

Canyonlands National Park: Biological soil crust is a living groundcover that forms the foundation of plant life in Canyonlands and the surrounding area. Join ranger Karen Henker for an in-depth look at this critical, and fragile, component of the high desert ecosystem.

Canyonlands National Park: The geologic history of Canyonlands spans hundreds of millions of years. Join ranger Karen Henker for a brief tour of this complex and exciting story.

Canyonlands National Park: Throughout Canyonlands, naturally occurring sandstone basins called potholes form tiny ecosystems inhabited by a surprising collection of animals. Join ranger Karen Henker for an introduction to these animals and some their remarkable adaptations.
