1951 Map of Port Alexander B-3 and B-4

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.
