Inside the tunnel clearly wanting a tripod. The tunnel face was about
the size of an ordinary door. Overnight, the ice deep in the tunnel
would try to close. The walls would move inward a couple of inches.
You didn't want to leave tools leaning against the wall as they could
get trapped and require chipping out. I gather some of the highest
strain rates ever measured at the time in ice were measured in the tunnel.
