About this map

The John Day Fossil Beds National Monument occupies the southwest portion of this landscape, where the deeply incised drainage of Devils Gulch and McCarty Cr meet the upland plateaus of Grant County. This high-desert terrain is defined by a series of named flats and meadows, including Miller Flat, Sunflower Flat, and Rudio Meadows, which suggest a history of seasonal grazing and high-altitude water management.

A network of springs and reservoirs, such as Waller Reservoir Number One and Burnt Corral Springs, supports the various creek systems that dissect the hillsides. Transport through this area is largely limited to the corridors of Holmes Creek Rd and Willow Creek Rd, following the natural contours of the drainages like Rudio Cr and Holmes Cr. The abundance of specific water sources, from Junction Springs to Mule Pasture Spring, reflects the critical importance of reliable water in this part of Oregon.
