Wortmanns Glacier and the adjacent ice fields of the Chugach National Forest dominate this high-altitude landscape in the early twenty-first century. This survey by the U.S. Geological Survey details the immense glacial systems that define the geography of the Chugach Mountains, including the expansive Tasnuna Glacier in the northeast and Woodworth Glacier to the south. The map provides a precise record of the ice margins as of 2014, showing the contours of features like Deserted Glacier and the steep elevation changes across the region. With no roads or permanent settlements present, the terrain is defined entirely by its glacial movements and the protected wilderness boundaries. This record of glacial coverage is vital for understanding the ice-dominated environment of the Unorganized Borough during this era.
