1989 Map of False Pass D-6

USGS Topo · Published 1989

About this map

Shishaldin Volcano anchors the southwestern landscape of this survey, marking a dramatic topographic high point on Unimak Island. The terrain is characterized by the extreme elevations of the eastern Aleutian range, including the jagged profiles of Isanotski Peaks and the descriptive Ragged Jack. Much of this territory is preserved within the Aleutian Islands Wilderness, where the land drops away from glacial peaks toward the shoreline of Bristol Bay. Waterways like North Creek and Coal Creek drain the northern slopes, illustrating the drainage patterns from the volcanic highlands to the sea. This 1989 provisional edition captures the raw geography of the island before modern shifts in glacial coverage, providing a base for studying the volcanic morphology of the Alaska Peninsula region.
