2018 Map of Jordan Meadow NW

About this map

The high desert borderland where Oregon and Nevada meet is defined by a network of seasonal drainages and topographic ridges. Much of the southern portion of this landscape is occupied by the expansive Jordan Meadow Flat, a prominent basin floor positioned below the Sentinel Hills. This 2018 survey illustrates how the drainage patterns of the Great Basin dictate the geography, with McDermitt Cr and Washburn Cr carving through the terrain. The presence of Long Ridge provides a significant vertical break in the landscape, separating the various branches of Little Washburn Cr and Wildcat Cr. For those studying the remote border regions of Malheur and Humboldt counties, this map provides the exact placement of these watercourses and landforms as they existed in the early 21st century.
