San Gabriel Dam construction, showing a man examining a truck, 1936

Photograph of San Gabriel Dam construction, showing a man examining a truck, 1936. The man in a lightly-colored suit and hat stands on the right, bending slightly at the waist. He holds paper and a pen in his left hand as he points beneath the massive towing bed of the large truck at center. The truck is stained with the dust and dirt of the surrounding terrain. Trees can be seen across the hills in the background.
