Mount Woolsey

Mount Woolsey is a summit in the Bighorn Mountains that rises to approximately 12,978 feet and forms part of a dramatic ridgeline. The peak connects to neighboring Black Tooth Mountain and Cloud Peak through a sharp ridge system within the Cloud Peak Wilderness area.

The peak was named in 1961 to honor Theodore Salisbury Woolsey Jr., a climber connected to the local area. Its first recorded ascent occurred in 1933 when W.B. Willcox, Alan Willcox, Mary Willcox, and T.H. Rawles summited from the south ridge.

The mountain received its name in 1961 to honor Theodore Salisbury Woolsey Jr., father of Elizabeth Woolsey who was part of the climbing group.

Reaching the area requires driving a high-clearance vehicle from Sheridan along Route 26 to Route 293, which passes through rough terrain toward Bighorn Reservoir. From there, most climbers continue on foot to approach the summit.

A small glacier sits on the southeast face of the mountain, adding an unexpected feature to this high elevation peak. It ranks as the third highest summit in the entire Bighorn Mountain chain.
