1972 Map of Eldorado Pass

About this map

Eldorado Pass serves as a central divide in this high-desert landscape of eastern Oregon, where the headwaters of numerous creeks diverge across the Baker and Malheur County line. The terrain is defined by its complex drainage network, including North Willow Creek, Middle Willow Creek, and South Willow Creek, which carve through the high country surrounding Ironside Mountain. Evidence of land management and historical boundaries is prominent, from the Old Indian Reservation Boundary cutting across the center of the sheet to the Whitman National Forest land in the west. Small-scale water infrastructure like Murray Reservoir and High Horn Reservoir supports the ranching character of the area, further evidenced by the Ironside C&H Corrals. A remote Landing Strip and various Jeep Trails provide the only significant access through these canyons and gulches, such as Black Stump Canyon and Lake Gulch.
