"20262 Piping Water to Los Angeles," Keystone View Company, ca. 1915. The image shows a section of Los Angeles Aqueduct pipe extending from hills in the distance across a valley to where the photographer stood. Other than the pipe, there is no sign of development and the location is unknown. On the reverse is text about the Los Angeles Aqueduct project, written as if for school use. With curvature of the mount and slight edge rubbing, the condition is good.
