Alaska Basin, Mountain basin in Caribou-Targhee National Forest, Wyoming.
Alaska Basin is a high mountain valley in the Caribou-Targhee region featuring alpine lakes, granite rock formations, and meadows set among tall peaks. The surrounding mountains rise above 10,000 feet and frame the entire landscape.
Glaciers during the last ice age carved out this valley through their slow movement across the landscape. The ice sculpted the granite formations and created the depression that now holds the alpine lakes.
The basin sits within a network of mountain trails that draws hikers from across the region seeking alpine experiences. Local mountaineers consider it an important waypoint in their exploration of the Teton peaks.
The hike is demanding and requires good hiking gear along with bear safety precautions for this backcountry area. Plan to start early in the day and bring plenty of water for the long trek.
The basin contains a clear mountain lake partway along the trail where visitors can see sharp reflections of the surrounding peaks on still days. Many hikers pause here to rest and enjoy the calm water.
