About this map

Fire Island sits at the convergence of several major Alaskan waterways, serving as a critical navigational hub for maritime traffic entering the upper Cook Inlet. Surveyed in the early 1950s, this area captures a landscape defined by expansive tidal flats and tactical strategic locations near the growing hub of Anchorage. The island is marked by its rugged shoreline features like West Pt and North Pt, alongside aviation infrastructure including a Landing Strip and two critical beacons, Fire Island Light and Race Point Light.

To the east and south, the map delineates the Point Campbell Military Reservation and the northern reaches of the Kenai National Moose Range. These designations reflect the dual 20th-century priorities of national defense and environmental conservation in the territory. Inland water bodies such as Diamond Lake and Cook Lake provide contrast to the massive silty expanses of the Susitna Flats and the mudflats of Chickaloon Bay, illustrating the complex coastal geography of the Turnagain Arm.
