1963 Map of Andies Prairie

About this map

Umatilla National Forest defines this high-elevation landscape along the boundary of Umatilla and Union Counties. The terrain is characterized by a series of prominent basaltic ridges and narrow canyons, with the North Fork Umatilla River and the Middle Fork Little Umatilla River draining the northern and central reaches. Natural clearings like Andies Prairie and Horseshoe Prairie break the dense woodland, while dozens of named water sources—including English Spring, Shamrock Spring, and Will Rogers Spring—suggest the critical role of water management for forest operations and recreation in this era.
