1952 Map of Healy A-4

About this map

The Jack River and its upper tributaries dominate this Alaskan interior landscape at the midpoint of the twentieth century. Steep topographic gradients define the drainage basins of the Tsusena River and the East Fork Chulitna River, illustrating the high-altitude watershed where these watercourses originate. The map documents a significant political and legal boundary between the Third Judicial Division and Fourth Judicial Division, which traverses the high ridges and crosses through Caribou Pass. This boundary, though marked as an Approximate Boundary, signifies the administrative partitioning of the territory prior to statehood. The presence of VABM 5854 Alt provides a specific geodetic reference point within the glacial-carved terrain, while smaller streams like Portage Creek and Soule Creek carve narrow paths through the surrounding peaks.
