Pete Lake is the headwater of the Cooper River, the most significant waterway of the Salmon la Sac region. The trail to the lake is one of the more popular hiking pathways on the east side of Snoqualmie Pass, with its diversity of uses and wildlife. It is enjoyable for campers, hikers, and birders. Climbers use it as a staging area for tackling Big Summit Chief and Chimney Rock.
