I went to Alibates a year ago. You have to schedule a time to see it. Its a sight to see. Bi faces, hammer stones, some of the most colorful flint I've ever seen. Those park rangers watch you like a hawk . Its an amazing walk through hell. Look & touch but you can't take any. There are other small deposits on priviet land. It sure is some purddy rock. Can't wait to see what ya make w/it.
