First, 6-10 feet of solid rock, "Overburden" of dolomitic limestone is
getting to the layer where the large pockets of crystals are.
Once the overburden
is removed (an area 10 feet high x 20 feet wide x 15 feet in depth and equal to
about 50 tons of rock -- this can take 2-3 months worth of weekends), he digs.
The next step is the hardest part, what we call, "Lifting the table" rock where
the pockets are.
