Medical Springs and the nearby settlement of Pondosa anchor this high-elevation landscape within the Whitman National Forest in eastern Oregon. The geography is defined by a complex network of alpine drainage systems, including Catherine Creek and its South Fork, alongside human-engineered water management features like Robertson Ditch and Wright Ditch. The presence of the Medical Hot Spring suggests a long history of local interest in the area's geothermal activity.
