About this map

Scott Glacier and Sheridan Glacier dominate this landscape within the Chugach National Forest, revealing a complex network of ice and water as they appeared in 1950. The map details the drainage patterns where the Copper River meets the coastal mountains, showing the transition from massive ice fields marked by extensive crevasses to the lowland water systems of Ibeck Creek and Salmon Creek.

Numerous smaller water bodies are clustered in the glacial wake, including Lake Elsner, the Siamese Lakes, and Beaver Lake. This record of the mid-century terrain preserves the exact positions of the Forest Boundary and the courses of the Rude River and Shephard Glacier, providing a baseline for researchers tracking the movement of these coastal ice sheets and the evolution of the surrounding watershed.
