About this map

Jordan Craters and the surrounding lava fields dominate this high-desert landscape in Malheur County, where volcanic activity has shaped the hydrology of the region. The centerpiece is the Cow Lakes system, divided by a constricted passage known as The Narrows. These reservoirs are vital to the local ranching economy, supported by Upper Cow Lake and Lower Cow Lake.

Remote outposts like Lodge Ranch, Anawalt Lake Ranch, and Terry Ranch are connected by a network of unimproved roads and a Jeep Trail, indicating the isolated nature of the terrain in the late 1960s. Water management is meticulously documented through features such as Oliver Reservoir and Boulder Reservoir, alongside natural drainages like Mahogany Creek and Schnable Creek. The presence of the Cow Lakes Recreation Area near the boat ramp highlights the area's dual role as a utility and a destination for outdoor enthusiasts.
