Men work on the Jacinto Tunnel beneath the mountains of Southern California.
Titles read: "UNDER CALIFORNIA'S MOUNTAINS".
California, United States of America.
Several shots of men working on the Jacinto Tunnel, 800 feet beneath the mountains of Southern California. Water pours in on the men from age-old water pockets as they work with pickaxes. Large steam shovels pick up the dislodged rocks. Men travel with the rocks in wagons on a railway track.
It looks like a pretty tough place to work in, with constantly rushing water and falling rock.
