2014 Map of Locust Grove

About this map

Locust Grove serves as the focal point of this high-plateau landscape, where the grain fields and canyons of the Columbia Plateau transition toward the river. The southern edge of the survey is defined by the winding course of the Deschutes River, which forms the boundary between Sherman and Wasco Counties. This river valley is a complex network of named drainages including Harris, Fall, and Mays, alongside the significant Harris Island within the river's flow. Further north, the terrain is characterized by long ridges and deep coulees, most notably Gordon Ridge and Mud Hollow. The map highlights a remote road network that includes the winding Rattlesnake Grade and Or-206, connecting these upland agricultural areas to the river below. Isolated water sources like Sand Spring and Wingate Spring are vital markers in this semi-arid environment, illustrating the geographic constraints on local settlement and ranching.
