Description
Photograph of an interior view of the West Portal Tunnel, part of the Mono Basin aqueduct project, ca.1920. The tunnel is cut out of solid rock, which is visible on the walls and roof. There are narrow railroad tracks running down the middle of the tunnel, and at center they split into two separate tacks before joining together again in the distance. A small hand cart ca be seen on the tracks at left. Several pipes and steel beams run along the inside of the tunnel, and a ladder is leaning against the wall at left. Switches similar to the one shown are laid ever one thousand feet.
