About this map

Chatham Strait and Frederick Sound converge in this mid-century maritime study, detailing the intricate coastline where Kuiu Island meets these deep Alaskan waters. The map focuses on the complex hydrography surrounding Security Bay, a sheltered inlet on the northwestern shore of Kuiu Island. Small-scale human activity is evidenced by a cluster of Cabins near the northern reaches of the bay, suggesting seasonal use within the Tongass National Forest.

The landscape is defined by its maritime hazards and navigational markers, from the isolated Yasha Island in the north to the jagged points and rocks like Indian Rock and Kingsmill Pt Vabm 28. The western edge of the sheet captures a portion of Baranof Island at Hoggatt Bay, illustrating the narrow passage through the strait that has long served as a vital corridor for the region's fishing and maritime trade.
