About this map

Baranof Island presents a complex coastline of deep fjords and glacial lakes in this mid-century survey. The terrain is dominated by steep peaks such as Rudakof Mountain and Ptarmigan Peak, which overlook a network of narrow waterways including Big Branch Bay and Snipe Bay. Small maritime settlements and research outposts are positioned at protected harbors, most notably Big Port Walter on the eastern shore and Port Armstrong further south. These locations were historically significant for fisheries and biological research within the Tongass National Forest.

The hydrography of the region is particularly dense, with numerous interior water bodies like Borodino Lake and Lonieof Lake feeding into the Pacific. The presence of features like the Kekur Peninsula and various offshore hazards like the Redfish Breaker highlights the maritime reliance of these isolated coastal communities. The mapping reveals a landscape where transportation was almost exclusively water-dependent, connecting points like Port Herbert and Port Conclusion to the open sea.
