1997 Map of Tash Peak

About this map

Beaverhead National Forest defines this high-country landscape along the Big Hole Divide, where the waters of the Dillon Ranger District split toward disparate drainage systems. The eastern slopes descend into the Grasshopper Valley, a wide basin where Grasshopper Creek collects the flow from numerous tributaries like Pole Creek and Middle Creek. The map documents a rugged topography punctuated by high summits such as Harrison Peak and Tash Peak, with isolated water features like Harrison Lake tucked into the high basins. Settlement is sparse in this mountainous terrain, with the Circle-S Ranch serving as a primary named landmark of human presence amidst the complex network of mountain passes, including Big Hole Pass. This late-twentieth-century revision provides a clear record of the access roads and forest boundaries at a time when traditional ranching and public land management intersected in the Pioneer Mountains.
