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.

Waterways like Honolulu Creek and the East Fork Chulitna River define the drainage patterns between prominent peaks such as Benbar and Chulitna. High-elevation crossings including Honolulu Pass and Broad Pass represent the primary gateways through the terrain. A solitary Jeep Trail in the northwest suggests the limited reach of ground vehicles away from the main rail artery during the mid-century era.
