Jimmy Smith, another volunteer member of the Tarrant County Archeology Society loosening rocks in the sinkhole floor.

If you're wondering what happens to all those rocks, this small tractor took a lot of them from around the cave entrance.

Once the entrance area was clear, a trailer was made available to remove rock from the entrance area.  Bryan Jameson and R.D. Milhollin just moved some.

There are now three rock piles as large or larger than this one.  A permanent monument to the diggers.

As the dirt is brought out of the cave, Bryan Jameson carefully marks each bucket as to what "zone" it was removed from.

This is the sinkhole floor after most loose dirt was removed.  The remaining fill was mostly rock with dirt mixed in.

Occasionally a small artifact(?) would be found creating some excitement.  This turned out to be part of an Armadillo shell - naturally occurring.

The cave is checked for signs of habitation or artifacts throughout the dig.  Some incidental flint chips and animal bones were found.

About 12' down, rocks were removed and these two small holes appeared.  Rocks could be heard falling for some distance.

The remaining rock is being removed, one worker and lots of supervisors.

When the hole opens up, Wayne Peplinski is the first one down with Ernie Parker monitoring his progress.
