About this map

Blue Mountain Pass serves as the central focal point of this high-desert landscape in Malheur County, where the infrastructure of water management dominates the map. The area is characterized by an extensive network of small impoundments and catchments, including Blue Mountain Reservoir Number One, Blue Mountain Reservoir Number Two, and Blue Mountain Reservoir Number Five, suggesting a region heavily utilized for livestock grazing. Notable landmarks like The Cap and The Table define the elevation changes across this arid territory.

Water sources are critical here, evidenced by the presence of Wash Rock Spring and Burnout Spring, alongside larger basins such as Basque Flat Reservoir. Transportation is limited to a few arterial routes like Crooked Creek Rd and Battle Creek Ranch Rd, which connect the isolated rangelands. This 2020 survey illustrates the continued reliance on scattered reservoirs like Crossroad Reservoir and Lone Star Reservoir to support activity in this corner of southeastern Oregon.
