About this map

Gareloi Island and the western reaches of the Andreanof Islands appear here as they were charted in the mid-twentieth century. Dominating the landscape is the massive Mt Gareloi, an active volcanic peak that defines its namesake island. To the east, the western peninsula of Tanaga Island is prominent, featuring the heights of Tanaga Volcano and coastal landmarks such as Cape Sajaka and Blackface Pt.

This hydrographic and topographic study focuses on the navigational hazards and landforms of the central Aleutians, detailing the treacherous passages like Amchitka Pass and Sea Otter Pass. The map traces the varied coastline of the Delarof Islands group, including the southern extremity at Amatignak Island. These landmasses and the surrounding waters, including the Petrel Bank, are preserved within the Aleutian Islands Wilderness, highlighting a period before modern maritime satellite tracking when these coastal profiles were essential for North Pacific navigation.
