2011 Map of Labyrinth Mountain

About this map

The Old Cascade Tunnel anchors the southwest corner of this high-elevation terrain, marking a significant engineering point in the crossing of the Cascades. The map details a complex network of alpine water bodies and drainages, including Minotaur Lake, Theseus Lake, and Lake Valhalla, which sit below prominent peaks such as Labyrinth Mountain and Mount McCausland. Along the southern corridor, Stevens Rd follows the course of Nason Creek, providing access to recreational sites like the Totem Girl Scout Org Camp. The landscape is defined by its steep glacial geography, illustrated by the sharp transitions from Union Gap down to the headwaters of the Rapid River. This survey captures the specific arrangement of Forest Service infrastructure and established campgrounds, such as the Theseus Creek Campground, at a time when these high-country routes remained essential for both transit and recreation.
