2020 Map of Blalock Mountain

About this map

Umatilla National Forest encompasses the high ridges and deep drainage systems of this portion of Umatilla County. The landscape is defined by the steep descent toward the S Fork Walla Walla River in the north and the complex network of mountain summits including Blalock Mtn, Weston Mtn, and Reed and Hawley Mtn. Water resources are a prominent feature of the terrain, from the Stone Hill Reservoir and Weston Pond to numerous named springs like Cold Spring and Dick Spring. The map documents a network of high-elevation access routes, including Lincton Mountain Rd and the Sf Walla Walla Trail, which trace the difficult topography of Tamarack Basin and Flume Canyon. This layout reflects a managed wilderness where early land use is marked by named summits and the vital movement of water through rugged gulches.
