04/2011 | White Hills, Mohave County, AZ | Paleo debris flow levees (dark lineaments) flank erosional scars (light areas) on the slopes of the White Hills in Mohave County, AZ. The light areas are light-colored due to exposed soil carbonate while the dark levees are dark-colored because they are composed of well-varnished basalt. (Photo by Joe Cook)
