Desolation Peak is a prominent mountain located in the Pacific Ranges mountain range of British Columbia, Canada. Rising to an elevation of approximately 1,478 meters (4,849 feet), it offers breathtaking panoramic views of the surrounding landscape. This mountain is known for its rugged terrain, making it a popular destination for experienced mountaineers seeking a challenging adventure.

During the winter season, Desolation Peak receives substantial snowfall, resulting in a considerable snowpack. The snowpack range can vary from year to year, but it typically accumulates from late fall to early spring, making it ideal for winter sports enthusiasts such as backcountry skiers and snowshoers.

Desolation Peak is bordered by several creeks and rivers that benefit from the mountain's runoff. These water sources include the Skookumchuck River, which flows to the southwest, and Lillooet River, which is located to the east. These rivers and creeks contribute to the overall beauty and ecological richness of the surrounding areas.

The history of the name "Desolation Peak" is rooted in the lore and legends of the indigenous people of the region. While different sources attribute various meanings to the name, it is commonly associated with the mountain's remote and desolate nature. This mountain has also gained literary significance, as it was made famous by American author Jack Kerouac, who spent a summer working as a fire lookout on Desolation Peak in 1956. Kerouac's experiences and reflections during his stay on the mountain were later documented in his novel, "Desolation Angels."
