1987 Map of Edie Creek

About this map

The Continental Divide defines the high-altitude boundary of this 1980s topographic study, marking the rugged intersection of the Beaverhead National Forest in Montana and the Targhee National Forest in Idaho. This high-country landscape is shaped by significant peaks and hydrological divides, including the Red Conglomerate Peaks and Knob Mountain. The drainage patterns here are distinct, with Medicine Lodge Creek and Edie Creek carving through the southern terrain, while Beaver Creek flows through the northern reaches near The Thumb. The presence of named features like The Bull Pen and Horse Mountain suggests a landscape historically utilized for livestock and transit through these high passes. This provisional survey captures the complex drainage systems and state-line boundaries at the height of the modern mapping era before digital transitions.
