Do you think that the debris field from the most massive flood that would have ever happened, would have been invisible in core sections? Is this really what you want us to believe? Core "resolution" does not make evidence disappear. There is no ~4500 year unconformity in the grenada crater lake core sections. I'll take this data as a confirmation that your 4500 year global flood did not happen.You're counting on a one year deposition being observed in decadal resolution core slices. I'll take lack of such as inconclusive.
Don't you think it miraculous how those little diatom shells resisted all sorts of turbulence so they could line up forming the well preserved "chronological sequence" found in the grenada crater lake core sections?
