Casper Mountain, Mountain in Natrona County, Wyoming, US

Casper Mountain is an anticline at the north end of the Laramie Mountains, rising to 8,130 feet (2,478 m) about 3,000 feet above Casper and the North Platte River. Its core exposes Precambrian quartzite, biotite schist, gneiss and amphibolite, with the Casper Mountain fault on the north side. The summit holds the Hogadon Ski Area, and trails for hiking, mountain biking and horseback riding cross the largely private land.

Archaeological evidence shows that people lived in this region about 11,000 years ago, leaving behind tools and artifacts. Items found from between 4500 and 2500 BC reveal that the area was an important place for tool-making and human activity.

The Beartrap Summer Festival brings bluegrass musicians to Beartrap Meadow each year, creating a gathering place for people throughout the region. The event has become a regular meeting point where locals and visitors enjoy live music together.

The mountain is easy to reach from the city and offers activities year-round, with winter sports in cooler months and hiking trails for warmer seasons. Visitors should bring layered clothing and plenty of water, as conditions change with elevation and weather shifts quickly in the mountains.

Casper Mountain is an anticline at the north end of the Laramie Mountains, and its rocks are older than those under Casper itself. Archaeologists have found stone artifacts dating to 4500–2500 BC near quartzite outcrops, where campsites suggest the rock was worked into tools and arrowheads. The University of Wyoming runs an archaeological site on the mountain.
