2014 Map of Matney Flat

About this map

Matney Flat and the surrounding high country of Gilliam County are defined by a complex network of seasonal drainages and named ridges. The geography is dominated by deep incisions such as Sixmile Canyon and Stackhouse Canyon, which feed into larger systems like the E Fork Thirtymile Cr and Rock Cr. This landscape reflects the ranching and agricultural patterns of eastern Oregon, where movement is dictated by the canyons and ridges. Local history is anchored at the Papersack Cem, situated near Papersack Canyon. Notable landmarks like Black Butte and Pine Ridge provide significant orientation points across the high plateaus. The road network, including Or-206 and Lonerock Rd, follows the natural contours of the land, connecting disparate canyons like Springston Canyon and Graham Canyon.
