2014 Map of Johnny Creek Spring

About this map

The Saddle Butte Lava Field dominates the high desert landscape of Malheur County, where volcanic geography meets the drainage systems of the eastern Oregon interior. This 2014 survey documents the rugged intersection of the Sheepshead Mountains and Cone Ridge, a terrain defined by intermittent water sources vital to the region's ecology. Named water features like Johnny Creek Spring and the ephemeral Palomino Lake provide critical points of reference in an otherwise arid expanse. The map traces the course of Ryegrass Cr and its tributaries, including the N Fork Ryegrass Cr and S Fork Ryegrass Cr, while showing the thin ribbon of Or-78 as it cuts diagonally across the volcanic plains. This survey is a precise record of public land subdivisions and hydrographic features in a sparsely populated corner of the state.
