About this map

Mount Veniaminof dominates this Alaskan landscape, captured during a 1963 field annotation. The massive volcano's summit is marked by a prominent Crater, surrounded by an extensive network of ice and geological activity. Glacial movement is central to the area's geography, with the Cone Glacier, Fog Glacier, and Island Glacier carving through the high elevations. The presence of Crevasses and fields of Lava emphasize the volatile, ever-changing nature of this volcanic terrain.

Water runoff from these ice masses feeds the major drainage systems of the region. The Muddy River flows to the northwest, while the Sandy River winds through the lower elevations to the southwest. This document reflects the state of the terrain as mapped by photogrammetric methods from aerial photographs taken in 1957 and 1962, showing the land before modern environmental shifts altered these significant ice fields.
