1950 Map of Healy A-5

USGS Topo · Published 1971

About this map

The Alaska Railroad cuts a critical industrial path through this interior landscape, following the corridor of the Middle Fork Chulitna River as it navigates the high passes. This 1950 field-annotated survey documents the small settlements of Colorado and Broad Pass, which served as vital points along the rail line for maintenance and transit. The presence of the Mile 305 Landing Strip and another Landing Strip near Colorado highlights the reliance on bush aviation to supplement the iron road in this demanding environment.
