1972 Map of Eldorado Pass

About this map

Eldorado Pass stands as a central topographic crossing in this high-elevation landscape on the border of Baker and Malheur counties. The terrain is defined by the steep slopes of Ironside Mountain and the complex drainage of the Willow Creek system, including Middle Willow Creek and South Willow Creek. The presence of the Old Indian Reservation Boundary cutting across the center of the map suggests the deep historical layer of land management and surveying in this region.
