Twin Lake, Upper

Upper Twin Lake is found in the Rattlesnake Creek Drainage of the East Pioneer Mountains. The shoreline is composed mostly of boulders with surrounding forested areas. Upper Twin Lake does not have an inlet but fish can be found in the outlet. Finding a dry spot around the lake can be tough especially in early Summer.
