About this map

The Kachess Lake region in the early 1960s was a landscape shaped by both massive water storage projects and the deep backcountry of the Wenatchee National Forest. At the southern edge of the sheet, the town of Easton serves as a gateway near the Kachess Dam, where the Yakima River flows toward Lake Easton State Park. This period shows the complex hydrology of the Cascades, with Cle Elum Lake and Little Kachess Lake functioning as critical reservoirs.

Resource extraction and wilderness access define the higher elevations, marked by the Eisnol Mine and a Strip Mine on Cle Elum Ridge. Extensive trail systems, including the Escondido Trail and the Jolly Mountain Lookout Trail, suggest a transition toward recreation and forest management. Features like the Salmon la Sac Guard Sta and the Easton Airstrip highlight the logistical infrastructure required to manage this vast timber and water resource.
