Photograph of a crane lowering a pipe into a trench on Yosemite Drive in the Eagle Rock Drainage District, September 27, 1936. The trench is at left and is a narrow cut that is supported by wooden beams. A road runs parallel to the trench at right, and a large flatbed truck can be seen parked nearby with a section of pipe on the bed. In the background, the arm of the crane can be seen lowering another section of pipe into the trench. Several workers can be seen helping to maneuver the pipe into the ditch. Photoprint reads "72 inch pipe into trench on Yosemite Drive east of La Roda Drive".
