1952 Map of Tyonek A-2

About this map

Cook Inlet dominates this mid-century hydrographic study, revealing the shifting shoals and tidal flats of the upper reach near the Susitna River mouth. The northern coastline is defined by the expansive Susitna Flats and heavy deposits of Mud, which create a complex navigable environment. Along the southern shore, the boundary of the Kenai National Moose Range encompasses the rugged coastline near Point Possession. The mapping shows small clusters of Cabins and a lone Cabin situated near the mouth of Miller Creek, indicating the sparse seasonal or subsistence residency typical of this coastal region before modern development. Detailed soundings across the inlet floor and the prominent Moose Point Shoal provide a record of the underwater topography as it existed in the early 1950s, essential for navigating the extreme tidal ranges of this Alaskan waterway.
