2015 Map of Coso Junction

About this map

The Los Angeles Aqueduct and Second Los Angeles Aqueduct dominate the eastern slopes of the Sierra Nevada in this 2015 study of Inyo County. These engineering marvels parallel the edge of the Mojave Desert, cutting across a landscape defined by significant drainage features like Tunawee Canyon, Portuguese Canyon, and Water Spout Gulch. Small highway settlements and transit points such as Dunmovin, Coso Junction, and Sykes sit along the corridor between the steep Haiwee Ridge and the floor of Rose Valley. The map detail captures the intersection of critical California water infrastructure with the arid terrain of Portuguese Bench and Lewis Canyon. Local history and geography are preserved through specific landmarks like Rose Spring and the curiously named settlement of Talus, providing a clear view of how high-desert geography and industrial utility meet in this part of the Owens Valley region.
