These are pictures of a native rock quarry that is on a piece of land I used to own in Big Bend its about 300 ft up the south side of Black Mesa which has a large volcanic blowout on the north side. This area was once a shallow sea and this ledge of chert is held in place by limestone. The volcanic activity lifted the limestone bedrock up. There are large hammer stones near the outcropping and you can see where the natives were knocking out pieces, down below on level ground is an area that is covered with flakes, where the natives either flaked the material into preforms or points.
