About this map

The Saddle Butte Lava Field dominates this volcanic landscape in Malheur County, recorded by the U.S. Geological Survey during the early 1970s. The terrain is defined by its basaltic features, including the distinct formations of Saddle and Butte in the northwestern quadrant. These geological structures, alongside Iron Mountain to the south, illustrate the raw topographical character of the high desert before extensive modern development.

A notable curiosity for local history and geology is the Owyhee River Cave, located near the northern edge of the lava field. Connectivity across this often-unforgiving ground is limited to a sparsely distributed Jeep Trail, highlighting the area's isolation. The map meticulously tracks elevation changes, including a small Falls in the southeast, providing a detailed record of the drainage patterns and rocky outcrops that define this remote corner of Oregon.
