Tunnel from 18 to 19

Underground steam tunnels connect many of the buildings at Whitby Psych. Without a flashlight, you see nothing - they are pitch black. This shot was a 15 second exposure and I used my flashlight to add extra illumination during the exposure. This section was wide enough to walk through fairly comfortably, but in some places they get narrow due to the steam pipes(ie: 1.5' wide).
