1967 Map of Flagstaff Lake

About this map

Flagstaff Lake dominates this high-desert basin in Lake County, Oregon, revealing a complex hydrological system of intermittent water bodies known collectively as the Warner Lakes. This 1967 field-checked survey illustrates the transition from the arid Alkali Flats to the significant depths of Mugwump Lake, Swamp Lake, and Anderson Lake. To the east, the dramatic elevation of Hart Mountain rises sharply from the basin floor, serving as a backdrop for the Hart Mountain National Antelope Refuge. The landscape is defined by its geological extremes, from the rugged Mulkey Canyon and the Rabbit Hills to the seasonal pools and springs that sustain the local wildlife. A solitary Jeep Trail and a few unimproved roads provide the only access through this sensitive ecosystem, while a Gravel Pit indicates localized resource extraction near the refuge boundary.
