1961 Map of Logan Valley

About this map

Logan Valley is a high-altitude basin within the Malheur National Forest, where the transition from mid-century ranching to forest management is clearly visible. The landscape is defined by its abundance of named springs and seasonal camps, reflecting a heavy reliance on water and timber. Functional structures like the OK Truck Barn, Summit Prairie Truck Barns, and the Lake Creek Guard Sta suggest a rugged working environment coordinated by the state and federal government. Settlement history is preserved in the form of cabins, such as the Davenport Cabin and Kimberling Cabin, while the Frost Mill (Site) marks the location of earlier industrial activity. The presence of several cow camps and the Summit Prairie railroad line indicates an integrated economy of grazing and logging that sustained the region through the early 1960s.
