About this map

Thorn Hollow and Stage Gulch anchor this pocket of Umatilla County, where the Umatilla River carves a path through a landscape of named ridges and canyons. The geography is defined by significant elevation changes, noted by features like Thorn Hollow Grade and the prominent Reservation Mtn. Local history is grounded at the Red Elk Cem, situated near the confluence of several drainages including Red Elk Canyon and Shaplish Canyon.

A complex network of seasonal and perennial watercourses, such as Wildhorse Cr, Isqúulktpe Cr, and the three forks of Spring Hollow Creek, suggests a terrain deeply shaped by erosion. Roadways like Cayuse Rd and Bingham Rd follow the natural contours of the river valley, while high points like Telephone Ridge, Kanine Ridge, and Gibbon Ridge provide a clear view of the area's agricultural and pastoral layout.
