1966 Map of Beulah

About this map

The North Fork Malheur River defines the central axis of this Oregon landscape, anchored by the Beulah Reservoir and the Agency Valley Dam. This 1966 topographic study captures the infrastructure of the high desert, including the Gaging Station and various reservoirs like Murphy Reservoir and Goldy Reservoir that managed water for the region. A notable cultural landmark is the Old Indian Treaty Boundary which cuts across the northern terrain near Castle Rock. Local history is preserved at the Agency Valley Cem near the small settlement of Beulah, while the southern reaches of the map show the transition toward the Union Pacific River corridor near Horseshoe Bend. The map is also dense with named natural springs, including Springs (Hot) and Moonshine Spring, which provided essential water sources in the arid environment between Agency Mountain and Bendire Mtn.
