A different shelter. This one had some large canine tracks in the dust in the back of it, either somebody's dog or a big-@$$ coyote. I don't think we have wolves around here...

They were in the dust by the back wall, near where Carolyn was standing...

More...

Supposedly they found some of the oldest human remains in N. America in this shelter. Here's a pic of some grinding holes that were in there...

“Grinding holes” you mean that people made to grind grains or ??? in? How cool! And are those stalagmites, or stalagtites in the other picture?
