About this map

Wrangell Island dominates this mid-century coastal survey, separated from the mainland by the sweeping waters of the Eastern Passage and Blake Channel. Within the dense forests of the Tongass National Forest, the landscape is defined by steep glacial features and narrow waterways. A lone Mine and scattered Cabins near Virginia Lake suggest the era's small-scale resource extraction and remote living.

The presence of Nelson Glacier and deep basins like Glacier Basin highlight the active glaciated environment, while maritime navigation is guided by landmarks such as Point Madan, Channel Island, and the restricted passage at The Narrows. This document records a time when coastal access via Berg Bay and river systems like Crittenden Creek remained essential for traversing this complex archipelago terrain.
