1958 Map of Tyonek B-6

About this map

Mount Spurr dominates this remote Alaskan landscape, anchoring a massive glacial network in the late 1950s. The survey reveals a dynamic frozen environment where the Triumvirate Glacier and Capps Glacier carve through the high terrain, marked by extensive crevasses that signify active movement. To the southeast, Crater Peak stands as a significant volcanic feature, with the map explicitly noting deposits of Volcanic Ash nearby, indicating recent geological activity. The presence of Strandline Lake at the edge of the ice field provides a clear point of reference for the shifting boundaries between ice, water, and rock. Unlike more settled regions, this map serves as a study in pure wilderness and the raw forces of glaciation and volcanism, recording the precise state of the Dogshead Glacier before later decades of environmental change.
