Mount Jefferson, located in Idanha, Oregon, is the second highest peak in the state and is known for its challenging summit pinnacle that requires Class 4 scrambling on steep, ice-encrusted rock. With over 5,777 feet of prominence, it is one of the 57 ultra-prominent peaks in the contiguous United States and is considered one of the most difficult volcanoes above 10,000 feet. Mount Jefferson offers various routes for mountaineering enthusiasts, including the popular Whitewater Glacier route and the Jefferson Park Glacier route.
Accessible via United States Forest Service roads and trails, Mount Jefferson can be reached from Oregon State Highway 22 through two main approaches: Jefferson Park and Pamelia Lake. While most routes on the mountain are considered dangerous due to rockfall and avalanche hazards, the ones described on Summitpost are considered the safest options. Mount Jefferson's geology, eruptive history, and geomorphology can be explored through the USGS Mount Jefferson page, and the mountain was named after President Thomas Jefferson by the Lewis and Clark Expedition.
