I like this guy already. Too bad most of what they need to find is off the coast on the contentinental shelf.
I do agree, most may be found on the continental shelf. However, the isolationist bias, which held that the Americas had been occupied for perhaps 3,000 years, and then around WWII retreated to the position that Clovis is as old as anything gets in the Americas, has prevented finds from being accepted. That's over a century of damage that has to be repaired wherever possible. The best way to do that is to dig on land. The finds are under there just waiting.
