2017 Map of Tyonek C-6 SW

About this map

Trimble Glacier and Triumvirate Glacier dominate this high-altitude landscape in the southern Alaska Range. The 2017 survey by the U.S. Geological Survey maps a region defined by massive ice flows and steep elevation changes, where the natural environment remains the primary narrative. The map illustrates the complex interaction between glacial movement and the surrounding peaks, providing a clear view of the drainage patterns and ice field boundaries as they existed in the early 21st century. This specific quadrangle covers portions of townships T18N R16W through T16N R16W, highlighting a wilderness area devoid of permanent human infrastructure, settlements, or roads, focusing instead on the topographic reality of the Matanuska-Susitna Borough's glacial interior.
