About this map

Blue Mountain Pass anchors this high-elevation landscape in Malheur County, where the infrastructure of water management and communication is etched into the high desert. This 1982 survey reveals a complex network of seasonal resources, including Basque Flat Reservoir, Blue Mountain Reservoir No 2, and the notably isolated Lone Star Reservoir. The names reflect both the ranching heritage and the physical challenges of the terrain, with features like Horse Corral, The Table, and The Gap providing essential landmarks for navigation.

Technological layers of the late 20th century are evident through the presence of a Radio Facility and a Single Wood Pole Transmission Line that traverses the northern slopes. The map also documents the unseen movement of resources through an Underground Water Pipeline and several buried lines connecting remote springs such as Wash Rock Spring and Summit Spring to various reservoirs, illustrating the intensive efforts required to sustain livestock and land use in this arid region.
