1972 Map of Rastus Mtn

About this map

Whitman National Forest and Malheur National Forest converge in this high-elevation terrain, defined by a complex network of 19th-century water infrastructure. The map illustrates the legacy of regional mining through the extensive paths of the Eldorado Ditch, Williams Ditch, and Johnson Ditch, which once carried water across the divide to gold claims. These engineering works wrap around the flanks of Rastus Mtn and Bullrun Mountain, connecting remote drainages like Whiskey Gulch to the broader watershed. Notable sites of early extraction remain visible, including the Thomason Mine and Schwayder Mine near the northern boundary. Dozens of named water sources like Hole in the Ground Spring and Lost Cow Spring are documented, highlighting the importance of reliable water for both historical mining operations and the grazing interests of Baker County.
