2017 Map of Tyonek B-7 SW

USGS Topo · Published 2017

About this map

Glacial ice and glacial runoff dominate this portion of the Kenai Peninsula, where the Harpoon Glacier and Pothole Glacier define the high elevations of the landscape. The terrain is marked by the complex drainage systems that feed into the Nagishlamina River, which winds southwards through the quadrangle. The lack of roads or established settlements emphasizes the raw environmental character of this region, which remains primarily defined by its hydrological and cryospheric features. For researchers of Alaskan geography, the map provides a clear record of these water bodies and ice fields as they existed in the early 21st century, showing the physical relationship between the permanent ice and the river systems that drain the high country.
