Pettit Lake, Glacial lake in Blaine County, Idaho, United States
Pettit Lake is a glacial lake in the Sawtooth Mountains of central Idaho, set in a valley basin formed by ancient ice activity. The clear waters reflect the steep mountain peaks and granite slopes that rise around it.
The lake took shape during the last Ice Age when glaciers carved a deep basin into the valley below. This glacial sculpting created the steep walls and granite formations visible today around the shoreline.
Local fishing traditions center around the lake's population of Kokanee salmon, Rainbow trout, and Bull trout, with specific catch regulations for each species.
The lake is easily reached by hiking trails and forest service roads that connect to the main highway nearby, with camping areas scattered through the surrounding forest. Plan for cooler temperatures and changing weather conditions due to the high elevation.
The water from this lake flows into neighboring water bodies through a chain of natural connections, becoming part of a larger river system. Few visitors realize how this small alpine lake feeds into downstream ecosystems many miles away.
