About this map

Lake Abert dominates the eastern edge of this high-desert landscape in Lake County, where the water's edge meets the steep slopes of the Coglan Buttes. The hydrology of the mid-1960s is defined by the Chewaucan River, which winds through the central valley toward the Lower Chewaucan Marsh. This area is characterized by drainage patterns including Willow Creek, Juniper Creek, and Crooked Creek, all flowing through a basin marked by an extensive Alkali Flat.

Evidence of local habitation and land use is sparse but significant for researchers, anchored by the Elder Ranch situated near the valley floor. The map documents several Jeep Trails that provide access through the Big Basin and surrounding uplands. Industrial activity is indicated by a Gravel Pit and a lone Water Tank, illustrating the isolation and specialized land use in this part of the Oregon backcountry during the post-war era.
