Cannibal Plateau, Mountain summit in Hinsdale County, Colorado, United States.
Cannibal Plateau is a summit located within the Powderhorn Wilderness, characterized by dark basaltic rock formations and coniferous forests that transition to exposed alpine meadows higher up. The landscape shifts from shaded woodlands to open terrain as you gain elevation.
The dark rock layers visible across the plateau formed from volcanic eruptions roughly 16 to 19 million years ago when lava flows created what is now called the Hinsdale Formation. This ancient geological activity continues to shape the mountain's appearance today.
The plateau stands in Hinsdale County, which contains five peaks above 14,000 feet and remains one of the most undeveloped mountainous regions in the United States.
Access to this summit starts at the Powderhorn Lakes Trailhead, from which hikers ascend through increasingly rocky and exposed terrain. Mountain weather shifts quickly at higher elevations, so proper gear and awareness of conditions are essential.
The plateau's name comes from a grim chapter of mountain history, but today it stands as a peaceful place where solitude is nearly guaranteed. Few visitors venture here, making encounters with others on the trail uncommon.
