Their agriculture? They were hunter/gatherers for certain, Chuck. If they were agricultural, it would be as obvious as a footprint in the mud.
At any rate, their very lifestyle and hunter/gatherer nature makes it a fucking bitch to pinpoint them. Piles of bones and cooking areas are about all we have of Clovis. Go back a few more thousand years, we don't have shit. It is going to be next to impossible to decide who was here first. We've gotten lucky with some carbon in certain kill camps. That will not always be the case.
