About this map

Fire Island dominates the center of this maritime survey, positioned at the critical junction where Cook Inlet branches into Knik Arm and Turnagain Arm. The 1952 topography reveals the strategic and navigational importance of the area during the early Cold War era, featuring the Point Campbell Military Reservation and the Point Campbell ACS Station on the mainland.

Navigational aids like Race Point Light and Fire Island Light mark the treacherous shifting sands and extensive mud flats of Susitna Flats and Chickaloon Bay. To the south, the boundary of the Kenai National Moose Range begins at Pt Possession, illustrating the balance between military infrastructure and the preservation of the Alaskan wilderness. A solitary Landing Strip on the southwest tip of Fire Island provides a trace of the remote accessibility required for these coastal outposts.
