Actually, I was quoting Pete Enns’ BL blog post that was in the link I provided. A quick Google search turned up an article at the NCSE website on The Flood: Mesopotamian Archaeological Evidence. It takes a skeptical angle and is from 1988, but it lists the usual suspects for such an event: Ur 3500 BC, Kish 3000 BC and 2600 BC (two floods), Shuruppak 2900 BC. I’m sure a little digging would turn up more info.
