About this map

John Day Fossil Beds National Monument anchors the southwestern corner of this Grant County landscape, protecting a region defined by complex drainage networks and high plateaus. The terrain is characterized by the broad elevations of Miller Flat and Sunflower Flat, which are dissected by numerous waterways including Rudio Creek and Holmes Creek. These water sources were historically vital for local livestock and land management, as evidenced by the distribution of named sites like Burnt Corral Springs, Junction Springs, and Mule Pasture Spring.

Transport and water infrastructure are clearly delineated, with Holmes Creek Rd providing access through the canyons and the Rudio Creek Trl following the contours of the valley. Significant water management is visible in the north at Waller Reservoir Number One and Waller Reservoir Number Three. From the heights of Rudio Mtn down to the bottom of Devils Gulch, the map reveals a remote geography of springs and meadows, such as Rudio Meadow, tucked away in the high desert interior.
