1969 Map of Eightmile Canyon

About this map

The Indian Massacre Historical Monument stands as a somber landmark on the eastern edge of the Lemhi Range, overlooking the wide expanse of the Birch Creek Valley. This 1969 survey captures a transition from the high, timbered ridges of the Targhee National Forest and Challis National Forest to the arid alluvial fans of the valley floor. The geography is defined by a series of parallel drainages, including Eightmile Canyon, Windfall Canyon, and Surrett Canyon, which carve deeply into the mountain front. Historically significant pathways like the Mormon Trail and various stretches of Jeep Trail trace the movements of early settlers and miners across this landscape. Near the higher elevations, Bald Mountain Spring provides a vital water source in an otherwise dry, high-altitude environment marked by peaks like Bald Mountain and Mahogany Butte.
