About this map

The Alaska Railroad carves a critical corridor through the interior landscape, following the course of the Middle Fork Chulitna River as it traverses the high-altitude terrain. The small settlements of Broad Pass and Colorado serve as operational points along the line, with the railway marking mileposts such as Mile 300 and Mile 305. This era of mapping shows a reliance on remote infrastructure, including a Landing Strip and the Mile Landing Strip situated near the rail line to support mountain transit.

Waterways dominate the drainage patterns of the region, with the East Fork Chulitna River, Bull River, and Honolulu Creek defining the valleys. Surveyors established various triangulation points across the peaks, such as VABM 5205 Benbar and VABM 3448 Bull, to map the elevation changes leading toward Honolulu Pass. The presence of Antimony Creek and Coal Creek suggests the geological interests of the period, while numerous smaller tributaries like Hardage Creek and Crooked Creek feed into the larger Chulitna system.
