Unalaska and Dutch Harbor anchor this coastal landscape where the Bering Sea meets the Pacific Ocean. The map documents a critical maritime and aviation hub, centered on the infrastructure of Amaknak Island, which is connected by the Airport Beach Road. Notable landmarks include the Unalaska Airport and the historic Holy Ascension Cathedral Church Cem, reflecting the deep cultural roots of the area. The terrain is defined by dramatic elevations such as Mt Ballyhoo and Ulakta Head, overlooking protected waters like Iliuliuk Bay and Margaret Bay. Defensive and maritime history is evident at Bunker Hill and along Arkansas Beach, while the complex coastline is dotted with hazards and markers like Iliuliuk Reef, Tuscarora Rock, and Arch Rock. This modern survey details the interface between the industrial harbor facilities and the steep, glaciated valleys of the Makushin Valley and Table Top Mtn.
