Terrace Mountain, Mountain summit in Park County, Wyoming
Terrace Mountain rises to 8,002 feet and sits approximately 2.2 miles southwest of Mammoth Hot Springs in Yellowstone National Park. The peak is part of the Gallatin Range and requires off-trail travel to reach.
The Hayden Geological Survey named the peak in 1878 to reflect its location near the travertine terraces at Mammoth. The area was formerly called Soda Mountain and White Mountain before this naming.
This peak is part of a vast protected wilderness area where visitors connect with the natural landscape of Wyoming. The place offers a sense of solitude and direct contact with undisturbed terrain.
The peak is only accessible during warmer months and requires navigation equipment and climbing experience since no maintained trails exist. Visitors should have basic orienteering skills and be prepared for changing weather at higher elevations.
The peak sits above layers of travertine formed by the same hot spring processes that create Mammoth's white terraces. This underground mineral activity beneath the mountain connects it directly to one of the park's most well-known thermal feature zones.
