1995 Map of Fish Lake

About this map

The Blackfeet Indian Reservation boundary meets the high mountain peaks of the Sawtooth Range in this mid-1990s survey. The landscape is defined by its transition from the reservation foothills to the protected alpine regions of the Bob Marshall Wilderness and Lewis and Clark National Forest. Significant water features like the Swift Reservoir and the high elevation Fish Lake anchor the drainage patterns for Birch Creek and South Fork Blacktail Creek. Evidence of early water management is visible through the Miller Ditch near Twin Lakes. Dominant peaks like Split Mountain tower over the network of creeks and alpine springs, including Hell Roaring Spring, highlighting the geographic complexity of the continental divide's eastern slopes.
