Yep and the controversy continues. They shutdown Calico because it was getting so deep it was dangerous. the trenches were 30 feet deep in some places yet they were STILL finding lithics.
I was personally able to be involved with that dig and handled quite a few of those at the time. In fact I am very good friends with the one who was put on the job of discrediting all those and shutting it down.
“Why?”... “Because I need to keep my Gov job”.
I can PM you the link to a photo project of those lithics if you like. If I share it in public it will get shut down ASAP.
