Tamping in dynamite prior to blasting a section at Gilman. Holes that have been prepared are shown with electrical connections to the blasting caps and the dynamite. Joe Fear prepared the blasting caps on the surface. Bottom series of holes were detonated first to keep the miners from having to work so much loose debris - a true demonstration of the principle of gravity.

88) Abandoned drift
Format:

"All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their use—for example, haulage, ventilation, or exploration." -- Encyclopedia Brittannica
This drift is at the 16 level in the Gilman mine and has been abandoned. Water dripping through the ceiling carries minerals, forming stalagtites and stalagmites.
