After the dry run was complete, it was time to move on to the real thing: ice-on-rock. Mike made a plexiglass front to the cryostat so we could watch what was happening and still keep things moderately cold (also thanks to our friends burlap and bubble wrap). Here it is in its "double direct shear" starting position...
...and afterward. We successfully slid ice past rock with an applied normal load (~100kPa)
A toast of champagne to celebrate!
And a paper describing the apparatus is found
here.
