1989 Map of Unalaska A-5

About this map

Chernofski Sheep Ranch sits at the head of Chernofski Harbor, a rare point of named habitation on this portion of Unalaska Island during the late 1980s. The landscape is defined by its maritime connections, evidenced by names like Mailboat Cove and Mutton Cove, while the interior rises into peaks such as Mount Aspid and Round Top Mountain. This coastal area is deeply indented by fjords and inlets, including Station Bay and Surveyor Bay, leading into the protected expanse of the Aleutian Islands Wilderness. The terrain is marked by distinctive features such as Black Fox Cliffs and the double peaks of Big Butte and Little Butte, illustrating the volcanic and erosional forces that shaped the Aleutian chain. The map details a wilderness environment where human footprint is largely confined to the sheep ranch and the naming of navigational landmarks like Cape Aiak and Peacock Point.
