About this map

The Umatilla Indian Reservation dominates this mid-century landscape in Umatilla County, centered on the Umatilla River as it winds through deep canyons. The small settlement of Thorn Hollow sits along the river banks, serving as a focal point for the surrounding high-plateau terrain. Movement through this complex topography is defined by established routes like the Stage Road and significant landforms such as Telephone Ridge and Buckaroo Ridge.

Water sources are vital to this environment, with Wildhorse Creek, Eagle Creek, and Spring Hollow carving the north, while Squaw Creek and Bachelor Canyon drain the south. Genealogy and local history researchers can identify the Red Elk Cem and a small Gravel Pit near the eastern boundary. The map provides a look at the interplay between the river valley and the steep ridges like Kanine Ridge and Gibbon Ridge before modern development altered these traditional paths.
