Ibex Butte stands as a central landmark in this high-desert landscape of central Oregon, where a series of topographic features define the arid terrain. The map details a sophisticated network of water management features essential for rangeland survival, including Sartain Reservoir Number Two and a numbered series of impoundments such as Twelvemile Reservoir Number One. These man-made catchments are interspersed with natural water sources like Ibex Waterhole, Santry Waterhole, and Juniper Spring.
