2020 Map of Castle Rock

About this map

Castle Rock stands as the central landmark of this high-elevation terrain where the borders of Malheur, Grant, and Harney Counties meet. The landscape is defined by a dense network of water sources, including the Little Malheur River and numerous named springs such as Whisky Gulch Springs and Campspot Spring, which speak to the area's importance for range management and wildlife. A significant drainage system flows through the territory, marked by Lost Creek and the deep incision of Jerry Canyon. Human activity in this remote corner of Oregon is traced via Castle Rock Rd and Lost Creek Rd, providing access to features like Horse Flat Reservoir and Mouse Lake. The topographical detail captures a classic Western ranching and riparian environment, from the heights of Black Butte down to the creek beds.
