1950 Map of Healy A-4

USGS Topo · Published 1974

About this map

Caribou Pass sits at the northern height of this high-altitude landscape, serving as a primary drainage divide in the Matanuska-Susitna region during the mid-twentieth century. The area is defined by a dense network of alpine waterways, with the Jack River and Soule Creek flowing through steep northern valleys while the Tsusena Creek carves a prominent southeast path. The glacial and fluvial geography is further detailed by the East Fork Chulitna River and Portage Creek, showing a wilderness environment largely devoid of established roads or permanent settlements at the time of the 1950 field annotation. This 1:63,360 scale documentation highlights the drainage patterns and unmapped land lines of the Alaska interior before significant modern development reached these remote corridors.
