View of construction of the Los Angeles Aqueduct, showing a wooden track, ca.1910-1920

A large, riveted pipe, supported by concrete blocks, runs from the left foreground to the hill that sits at the center background. A wooden track runs along the ground, parallel to the pipe.

In the center of the image, two men lean on a cart that rests on the track. A metal apparatus with cables extending from the top, apparently used to hoist beams, sits to the right of the track. Hills are visible in the distance.
