This photograph is possibly related to a different photograph of the same event that appears with the article, “Aqueduct situation tense as investigators for city find unexploded case of dynamite: WATER GUARDS IN SECRET RIDE no-name canyon now alive with repair crews water soon fill flow into blasted siphon auto numbers may lead to arrest of outlaws,” Los Angeles Times, 31 May 1927: A12
Workers, seen from a worm's-eye perspective, carry out repairs on a blast-damaged section of an aqueduct pipe. The pipe is viewed close-up, entering frame at left and stretching across the foreground. At center, a ladder is propped up against the near side of the pipe. One worker stands on the ladder and leans over the pipe to carry out repairs. Behind and to the left of him, another man stands atop the pipe. He faces slightly right as he swings the tool he holds behind him. Another man is barely visible along the left edge, also standing on the pipe.

Below is a close-up of the conduit, showing the extent of the explosion and the crews at the repairs. [Photographs by George R. Watson, Times staff correspondent],” Los Angeles Times, 31 May 1927: A12
