Cull Buck,
If you don't mind me asking, where was the place you hunted?
We had a mule deer lease for a few years north east of Alpine in the Glass mountains, and there are some cool caves on the place much like you describe. There was even a burned out midden on the place that has been studied by archeologists for quite some time. It was a very interesting place, and we found some cool stuff there (In addition to some monster mule deer, elk, and aoudad.)
Here's an article about it. The ranch we had was the Mills Ranch.

The ranch we hunt is about 90 miles west of Del Rio on Hwy 90. The nearest town is Langtry which is about 30 miles to the east. The southern boarder to this 10,000 acre ranch is the rio grande river.
About 100 yards from this cave we found a midden site. We have found several of those plus lots of arrow heads on this ranch. Not to mention 6 feral mexicans.
