Fossil Mountain

Fossil Mountain is a summit in the Fish Creek Range that displays layers of sedimentary rock formations across its slopes and surrounding terrain. The exposed stone reveals different geological periods and depositional patterns that visitors can observe throughout the landscape.

The rock layers of Fossil Mountain were formed millions of years ago through deposits in ancient seas and lakes. Over time erosion has exposed these formations and now reveals insights into Earth's past.

The mountain area serves as a natural habitat for various raptor species, including bald eagles, peregrine falcons, and golden eagles in their native environment.

This summit lies southwest of Delta and can be reached via US Highway 6/50 through open country. Visitors should prepare for unpaved access routes and changing weather conditions at this elevation.

The mountain displays fractured rock layers with clearly visible fault planes that make the terrain look like an open book of Earth's history. These fault lines are uncommon to observe and make this location particularly interesting for those curious about geology.
