Palmer and Kaye have different conclusions. Palmer claims to show the dredge layer, but Kaye, actually, others included claim the sand, or dredge material wasn't pushed that far up the beach.
McPheters doesn't really give enough information about how many pieces were found, and logged. I read on the DZ that snowmman brought it to Bruce's attention.
Bruce, did you ever follow up trying to contact McPheters?
