About this map

The Wrangell Mountains dominate this high-altitude landscape, where several distinct administrative boundaries converge within one of the nation's most protected wilderness areas. This topographic survey documents the intersection of the Wrangell-Saint Elias National Park, the Wrangell-Saint Elias National Preserve, and the designated Wrangell-St. Elias Wilderness. The terrain is defined by its glacial activity and drainage patterns, with the Sheep Glacier and Drop Glacier feeding into the surrounding valleys.

Boulder Creek flows through the northern reaches of the quadrangle, carving through township and range lines that grid this otherwise roadless expanse. Unlike many coastal regions of the state, this interior section focuses on the high-elevation contact points between ice fields and alpine watersheds, such as the West Glacier area, providing a precise record of the environmental margins in the early twenty-first century.
