Photograph of San Gabriel Dam construction, showing men using jackhammers, 1936. About a dozen men stand on the dam site with matching work clothes and hard hats. A man with his shirt tucked in his side pocket shovels loose dirt in the foreground on the right while most of the other men dig at the ground with jackhammers. Large trucks drive along a curving dirt road around the hills in the background while a metal tower stands on the left.
