1963 Map of Blalock Mountain

About this map

The South Fork Walla Walla River cuts a deep path through the high country of the Umatilla National Forest in this early 1960s survey. The landscape is defined by its dramatic ridges and elevations, including Blalock Mountain and Lincton Mountain. Human activity is marked by remote outposts and forest infrastructure, such as the Demaris Cabin and a Gaging Station along the river. Transportation in this era relied on the winding Lincton Mountain Road and various Jeep Trails that traverse the steep terrain. The map also captures the Blue Mountain Camp and numerous water sources like Cold Spring and Dick Spring, which were vital for forest management and local travel before more modern developments. The presence of Flume Canyon suggests the historical importance of water management in this high-altitude drainage basin.
