Sawtooth Lake

Sawtooth Lake is a glacial lake in the Sawtooth Mountains with clear water held in a high mountain basin surrounded by steep rocky slopes. Iron Creek feeds the lake, and the shores are characterized by rocky terrain and alpine vegetation typical of high elevation areas.

The lake formed during the last ice age when glaciers carved deep basins into the mountain landscape as they moved across the terrain. Glacial processes created the bowl-shaped depression that now holds the water.

The lake draws people seeking solitude and connection with mountain wilderness, serving as a retreat for those who value time spent away from towns and roads. Visitors come to experience the feeling of being surrounded by high peaks and quiet spaces.

This lake sits at high elevation and is accessible only during warmer months when snow has melted away. The hiking trail to reach it is challenging and requires good physical fitness and proper outdoor gear.

The water contains remnants from the ice age that preserve scientific information about climate patterns from thousands of years ago. Researchers study these ancient water molecules to learn more about conditions during the glacial period.
