About this map

Kalgin Island dominates the central waters of Cook Inlet in this mid-century hydrographic and topographic study. The landscape is defined by its isolation, characterized by extensive Tidal Flats and marshy interiors drained by Swamp Creek and Packers Creek. To the west, the mainland coastline at Harriet Pt looks across Redoubt Bay toward the island's sheltered anchorages at Oldmans Bay and Cobbs Cove.

Grounded in aerial photography from the 1950s, the map reveals a sparsely developed frontier where seasonal human presence is noted only by a few isolated Cabins. This survey captures the natural state of the inlet's geography before significant modern infrastructure, showing a terrain shaped by heavy siltation and extreme tidal ranges that render much of the shoreline inaccessible by traditional land transit.
