About this map

Kenai Mountains ice fields dominate this mid-century survey, revealing a landscape defined by massive tidewater and alpine glaciers within the Chugach National Forest. The map documents the extensive reach of Portage Glacier and Spencer Glacier in the west, while the eastern coast is carved by the deep inlets of Blackstone Bay and Kings Bay.

Detailed hydrography and topography captured in the early 1950s show a complex network of named ice masses, including the Blackstone Glacier and Taylor Glacier, many of which terminate directly into the sea or create dramatic mountain basins. The presence of numerous labeled ice features like Whittier Glacier and Cotterell Glacier provides a clear record of glacial extent before modern recession, including the positioning of Willard Island within the Blackstone drainage.
