1995 Map of Anchorage A-1

About this map

Chugach National Forest encompasses this glacial landscape, where ice and seawater meet along the northern reaches of Prince William Sound. This 1995 revision, based on mid-century topography and 1990 imagery, documents the massive Columbia Glacier and its surrounding alpine environment. The map shows the glacier’s intricate network of branches, including the First Branch and the secondary Pedro Glacier, as they flow toward the sea. The southern edge of the sheet transitions from ice to open water at Columbia Bay and Long Bay. A notable feature is the Iceberg Impoundment Area near the glacier's terminus, a dynamic zone where ice meets the tide. Named inland water bodies such as Kadin Lake and Terentiev Lake are visible amidst the high peaks, including Columbia Peak and the prominent Great Nunatak, offering a clear look at the region's wilderness character before late-20th-century shifts.
