2016 Map of Valdez A-4 SW

About this map

Marshall Pass serves as a critical high-elevation transition point between the drainages of the Lowe River and the Tasnuna River. This 2016 survey illustrates the dramatic glaciated landscape within the Chugach National Forest, where massive ice fields such as the Tasnuna Glacier, Marshall Glacier, and Woodworth Glacier dominate the terrain. The map provides a detailed view of the natural water systems as they emerge from these glaciers, particularly the Tasnuna River as it winds through its valley. The lack of human infrastructure or established settlements on this sheet highlights the wilderness character of the Alaska range, focusing instead on the topographic details of the mountain peaks and the movement of glacial ice over time.
