2019 Map of Ugashik A-4 SW

USGS Topo · Published 2019

About this map

The Yantarni Volcano dominates the southeastern quadrant of this terrain, its glacial ice and steep slopes characteristic of the volcanic activity found along the Aleutian Range. This landscape is contained almost entirely within the Alaska Peninsula National Wildlife Refuge, where the drainage of Yantarni Cr cuts through deep valleys shaped by tectonic and volcanic forces. The map provides precise topographic detail of these remote peaks and high-altitude basins, illustrating the structural geology of the Alaska Peninsula in the modern era. The presence of these dramatic features highlights the geologic isolation of the region, where the intersection of volcanic peaks and glaciation defines the local topography.
