About this map

Glenns Ferry serves as the focal point of this mid-century landscape, positioned where the Union Pacific railroad and the historic Oregon Trail converge along the northern bank of the Snake River. The map highlights the town's geographic importance as a transit hub, featuring the famous Three Island Crossing, a vital river passage for early emigrants. The local economy and infrastructure are clearly defined by the King Hill Main Canal and the Landing Field, alongside smaller landmarks like the Slick Bridge and a Cem northwest of the main settlement.

To the south, the terrain breaks into deep draws such as Deadman Canyon, leading toward the Deadman Falls Dam and Deadman Flat. The presence of the King Hill Trail and a Historic Marker near the river reflects the deep layers of overland travel history etched into this Elmore County landscape. This survey, based on 1946 aerial photography, captures the area before modern interstate developments altered the traditional path of the old trails.
