1963 Map of Blalock Mountain

About this map

The South Fork Walla Walla River carves a deep path through the northeast corner of the Umatilla National Forest, anchoring a landscape defined by sharp ridges and significant elevation changes. Historically, the area serves as a rugged backcountry resource, evidenced by the presence of the Demaris Cabin and remote outposts like Blue Mountain Camp and McDougall Camp. Transportation through this territory is largely confined to ridge-top routes such as the Lincton Mountain Road and Basket Mtn Road, which provide access between the high peaks of Blalock Mountain and Weston Mountain. Water sources are vital in this terrain, with numerous named points including Cold Spring, Dick Spring, and a Gaging Station monitoring the river's flow near the mouth of Flume Canyon.
