2011 Map of Jordan Craters North

About this map

Jordan Craters and the distinct volcanic formations of Coffeepot Crater dominate this high-desert landscape in Malheur County. The western edge of the sheet is defined by the winding course of the Owyhee River, where the George Ranch stands as a notable human imprint on the remote riverbanks. Water management in this arid environment is evident through an extensive network of small impoundments, including Blue Canyon Reservoir, Glover Reservoir, and Wild Rose Reservoir, many of which are connected by primitive roads like Birch Creek Rd and Blowout Reservoir Rd. The topography is marked by basaltic features such as The Tongue, reflecting the unique geological character of the region. This 2011 survey captures the area's transition between volcanic fields and grazing lands, anchored by landmarks like Groundhog Reservoir and Holdout Reservoir that support the local ranching economy.
