About this map

Black Butte and the distinctive formation of Castle Rock anchor this high-desert landscape in Malheur County, where the Little Malheur River carves a path through a territory defined by its water sources. This 2011 survey documents a network of named springs and small catchments essential for life and land management in the Oregon interior, including Irish Spring, Campspot Spring, and Castle Rock Spring.

Human activity is concentrated along the arterial Lost Creek Rd and Castle Rock Rd, leading toward the southern reaches where Horse Flat Reservoir and the Hunter Campground indicate areas of modern recreation and livestock management. The map details a varied drainage system, from the South Bully Creek in the northeast to the numerous branches of Lost Creek and Spring Creek, providing a clear record of the area's hydrology and topography.
