About this map

Fire Island dominates the waters where Cook Inlet splits into the Knik Arm and Turnagain Arm. This mid-century survey reveals a landscape of massive mudflats, such as the Susitna Flats, and strategic military and navigational infrastructure. The island itself is marked by its Landing Strip and Gravel Pit, alongside vital navigation markers like the Fire Island Light and Race Point Light.

To the east, the mainland near Anchorage features the Point Campbell Military Reservation and the Point Campbell ACS Station, highlighting the area's significance for defense and communication in the early Cold War era. Farther south across the inlet, the map touches the northern tip of the Kenai National Moose Range at Pt Possession, showing the intersection of federal conservation efforts and essential maritime transit corridors.
