2020 Map of Bally Mountain

About this map

Bally Mtn serves as the focal point of this high-altitude landscape where the Umatilla National Forest meets the Whitman National Forest. The terrain is defined by a complex network of seasonal and perennial water sources, including distinctive features like The Narrows and the deep incisions of Cougar Canyon. The map reveals a specialized seasonal infrastructure, notably the 21 Road Snowmobile (Snow) route and various forest access ways like Rocky Ridge Rd and Forest Rd 5415. Local hydrology is marked by numerous named springs such as Horseshoe Spring, Wildhorse Spring, and Bally Mountain Spring, which feed into the drainage basins of Meadow Cr and E Birch Cr. This survey provides a modern record of the Umatilla and Union County border, showing the management of these protected forest lands in the early 21st century.
