This photograph has three images. The first image (0272_0032) shows the lower portals on the Arizona side. The handwritten inscription reads, "Each drill is connected with a water line to wash the drill dust out, and to aid the men in breathing. At end of shift the men come out the tunnels looking like chocolate soldiers, being covered red with mud out of the drilled holes. The temperature often reaches 126 degrees in tunnels. Glad I was a form raiser." The second one (0272_0033) reads, "Upper portals, working bridge for trucks. Taking muck from tunnels, using it to make temporary dam across river to direct water through tunnels." The third one (0272_0034) reads "First big blast in canyon as seen from road above canyon."
