B & W digital scan of Marian Steam Shovel excavating Trench for LA Aqueduct Siphon. Pipe sections at left of image will be placed in the trench and backfilled. "The most satisfactory results were obtained on the Aqueduct by laying pipe in a shallow trench that supports about one third of the bottom circumference of the pipe. This can be best done on gently slopes where the soil conditions are favorable." from LA Aqueduct Construction Final Report, Construction of Siphons, pg. 199.Collection
