Umatilla National Forest encompasses the majority of this landscape in the mid-1990s, defined by a network of springs and rugged ridges along the border of Morrow and Wheeler Counties. The presence of Corncob Ranch near the center of the sheet highlights the isolated agricultural operations that dot the drainages of Corncob Creek and Kahler Creek. Water management is central to this environment, evidenced by a Diversion Ditch and numerous stock ponds including Yellowjacket Spring and Crawford Spring that support ranching in the high country. High points like Collins Butte and the extensive Sourdough Ridge overlook deep basins and canyons such as Henry Dixon Basin and Stahl Canyon, where various quarries and gravel pits indicate localized resource extraction alongside established forest management.
