The tunnel is about a mile from here.
The section on the rock face was just the flume, supported on the inside by a ledge blasted out of the rock, and on the outside by vertical supports resting on small niches 20-30 feet below, also blasted out. There were also some suspension cables anchored above in places.
Here?s what it looks like up close. The ledge is about two feet wide. Composite photo, and yes, I need to go back and get better shots....
There?s a section of it between the distant view and here that I can?t get across.

But we are not looking at the tunnel. Was this a road? Too small to figure out.

When built around 1860, the Blue Tent ditch and flume was 30 miles long. It was eight feet wide on top, six feet wide on the bottom and four feet deep. Part of it was a tunnel cut through 1000 feet of granite. It carried water from the South Yuba River to the Blue Tent Mine.
