Thiel Glacier and the West Branch Taku Glacier define this high-elevation landscape within the Tongass National Forest. The map documents a complex system of ice fields and dramatic vertical relief, characterized by prominent landmarks such as the Icefall Spires and Horn Spire. The drainage patterns and glacial margins recorded in 2017 provide a precise baseline for studying the shifting ice of the Juneau Icefield. Significant peaks throughout the quadrangle, including Mustang Peak and The Tusk, serve as fixed points for navigators and glaciologists tracking the southern reaches of the Eagle Glacier and the northern extent of the Herbert Glacier. This area, devoid of permanent human settlements or road infrastructure, remains a primitive wilderness dedicated to the movement of ice and rock.
