About this map

The Glenn Highway serves as the primary artery through this interior Alaskan landscape, connecting isolated outposts and lodges during the early 1950s. The settlement of Glennallen sits at a critical junction in the east, supported by local establishments like the Glennallen Lodge and the I Bar F Lodge. The topography is defined by the winding course of the Tazlina River, which cuts through the southern portion of the quadrangle, fed by tributaries such as Moose Creek, Nickel Creek, and Durham Creek.

Further west, the Ranch House Lodge stands near the intersection of several water features, including Salt Spring and Mud Lake. The map reveals a post-war frontier transition where highway-dependent commerce began to solidify around natural water sources like Twin Lakes and Plumb Bob Lake. This survey provides a precise look at the early infrastructure of the Copper River basin before more extensive modern development reached the region.
