2017 Map of Tyonek C-7 NW
USGS Topo · Published 2017About this map
Hayes Glacier and Trimble Glacier dominate this high-elevation Alaskan terrain within the Matanuska-Susitna Borough. This 2017 survey illustrates a stark, ice-carved landscape defined by complex contouring and glacial movement within the boundaries of t19n r18w and t18n r18w. The map provides a detailed record of the glacial margins as they existed in the early twenty-first century, offering a baseline for studying the shifting ice mass of the Alaska Range. As a modern digital-era topographic study, it prioritizes precise elevation data and hydrographic flow across a region defined entirely by its glacial geology.
