2020 Map of Heart Mountain

About this map

Targhee National Forest dominates this high-altitude landscape in Clark County, where the southern reaches of the Beaverhead Mountains meet the high desert basins. The terrain is defined by dramatic elevation changes between Heart Mountain and Black Mountain, which overlook a network of seasonal drainages and canyons. The historical imprint of western migration is evident along the Emigrant Trail, which traverses the eastern slopes near Medicine Lodge Bench. This corridor reflects the long-standing importance of this pass for travelers crossing between Idaho and Montana. Water sources are scarce but significant in this environment, represented by the Antelope Lakes and Warm Springs at the southern edge of the quadrangle. The map details a landscape transition from the timbered heights of Grouse Canyon to the broad, arid expanse of Slate Basin, providing a clear view of the drainage patterns of Webber Creek and McNeary Creek.
