2017 Map of Blizzard Mountain South

About this map

Craters of the Moon National Monument dominates the southeastern and eastern reaches of this high-altitude landscape, marking a stark transition between the peaks of the Pioneer Mountains and the volcanic basalt flows of the Snake River Plain. The terrain is defined by dramatic elevation changes, rising from the basin near Lava Lake toward the heights of Blizzard Mtn and Pioneer Mtn in the north. This 2017 survey details a remote watershed where seasonal drainages like Copper Cr, Lava Cr, and the E Fork Fish Cr carve through deep ravines such as Barn Canyon. Human activity is sparse, primarily represented by unpaved access routes like Lava Lake Rd and E Fork Fish Creek Rd, which provide entry into the primitive backcountry and the protected wilderness areas at the edge of the monument.
