2017 Map of Tyonek B-7 SE

About this map

Mt Spurr dominates the landscape of this Kenai Peninsula region, its massive volcanic form surrounded by a complex network of moving ice. The 2017 survey by the U.S. Geological Survey details the high-elevation glacial environment where Pothole Glacier and Capps Glacier originate from the steep slopes of the Tordrillo Mountains. To the south, Barrier Glacier and Crater Glacier illustrate the dynamic ice formations that define this unpopulated wilderness. The map provides a precise look at the township and range boundaries, such as t15n r18w and t14n r17w, tracing the high-altitude contours and drainage patterns that feed into the lower basins. The elevation data reveals the stark prominence of Mt Chichantna, a significant landmark for navigating this remote Alaskan terrain.
