The digging was done by a crew of 6. One would make the cuts diagonally
outward on the face of the tunnel with the chainsaw, then chip out the
wedges on the sides with a pick or jackhammer. Then the jackhammer would
be placed in the middle of the face causing the whole thing to shatter.
That got you about a foot of new tunnel. The second person would then
shovel the newely freed ice and put it in the sled shown here. The
third person would take the sled to the tunnel mouth and dump it. The
other three people would be resting. At some interval I forget, we
would rotate. Barklay thought that was too much resting, until he tried
it.
