Malheur National Forest dominates this landscape in Grant County, defined by a complex network of ridges and drainage basins. The southern reach of the map is anchored by the South Fork John Day River, where Morgan Cr and Poison Cr contribute to the valley's watershed. High elevations are marked by distinctive peaks such as Graylock Butte, Frenchy Butte, and Big Baldy, providing a look at the geographical layout before the turn of the millennium.
