About this map

Kupreanof Island dominates this mid-century topographic study, showcasing a landscape of complex waterways and dense wilderness within the Tongass National Forest. The map documents the intricate drainage patterns of the region, from the northern Irish Creek and Irish Lakes down to the southern shores of Totem Bay. The western edge is defined by the tidal interface of Keku Strait, where Tunehean Creek and Lovelace Creek meet the saltwater.

Detailed hydrographic data from the early 1950s provides a precise look at inland features like Kushneahin Lake and the winding course of the Castle River. This survey represents a period when mapping relied heavily on 1948 aerial photography and limited field annotation, capturing the raw geography of the Alexander Archipelago before modern developments. The lack of roads or established trails on the sheet emphasizes the maritime-dependent nature of travel and resource access in this part of Southeast Alaska.
