1956 Map of Eagle C-5

About this map

High-altitude interior terrain dominates this mid-century survey of the Alaska frontier. The landscape is defined by the sharp drainage of Ruby Creek in the southeastern quadrant and the prominent elevation of Copper toward the north. Mapping efforts by the U.S. Geological Survey during this era relied on aerial photography from 1954 and 1955 to chart this unsurveyed territory. The lack of established roads or settlements on this sheet reflects the wilderness character of the region before significant modern development, showing instead the natural contours and watercourses as they were first recorded for the Bureau of Land Management.
