About this map

Deep drainages and narrow ridgelines define this section of the Oregon high country where Gilliam and Morrow counties meet. The landscape is characterized by a complex network of seasonal and perennial waterways, including the upper reaches of Lone Rock Creek and its tributary, Lob Fork. Significant topographical features like Hale Ridge and Pine Ridge provide high-ground transit corridors, evidenced by historical routes such as Hale Ridge Rd and Hail Ridge Rd that follow the natural contours of the land.

Several prominent canyons, including McPherson Canyon, Lyons Canyon, and Billy Canyon, cut through the terrain, suggesting a landscape shaped by significant erosion. To the south and west, the map transitions into the watershed of East Fork Thirty-mile Creek, while northern drainages like West Fork Dry Creek and East Fork Dry Creek illustrate the radial drainage patterns of the area's prominent ridges.
