About this map

The glacial reaches of the Chugach Mountains dominate this mid-century survey, defined by the immense Woodworth Glacier and Schwan Glacier. These massive ice fields flow between towering summits like Cordova Peak and are heavily marked by crevasses, reflecting the dynamic mountain landscape before modern shifts in ice volume. In the lower elevations, the Rude River and the mighty Copper River carve through the terrain, providing the primary hydrological features of this part of the Chugach Nat Forest.

The map provides precise geodetic markers such as VABM Worth 3789, which served as critical survey points for the Bureau of Land Management in an era when much of this territory remained unsurveyed and unmarked. The transition from the high-altitude Tasnuna Glacier to the river valleys captures a raw Alaskan wilderness at a time when aerial photogrammetry was first being used to document its scale.
