2015 Map of Snag Hill

About this map

Ice Caves and high-elevation volcanic features define this 2015 survey of the northern Cascades landscape. Located within the Shasta National Forest, the terrain is marked by distinctive geological formations such as Obsidian and the prominent Ice River Ridge. The network of Forest Service roads, including Powder Hill (FA49), provides access to a series of summits including Snag Hill, Papoose Hill, and Harris Mtn. Water is scarce in this porous volcanic environment, represented here by Lava Creek Spring and the Lava Crack Spr trail or road. The map captures a modern view of this protected wilderness, showing the intersection of Township and Range boundaries across a landscape shaped by ancient lava flows and subterranean ice formations.
