About this map

Nabesna Glacier dominates this high-altitude landscape in the Copper River Meridian, captured as it appeared during a 1960 field annotation. The terrain is defined by massive ice fields and narrow mountain corridors, such as Mountaineers Pass, reflecting a region of extreme vertical relief. This area is notably characterized by its lack of human infrastructure; the Bureau of Land Management identified these land lines as unsurveyed and unmarked at the time of publication. The inclusion of the Base Line survey marker serves as a rare point of orientation in an otherwise wilderness-heavy quadrangle. This document provides a record of glacial extent and topographical features before later environmental shifts, serving as a primary reference for the physical geography of this portion of Alaska.
