Their theory: these older sediments hold the greatest potential for holding late Pleistocene (older than about 11,000 years) or early Holocene sites.

I learned that in grad school! If you want a 10,000 year old site, better find 10,000 year old dirt.

"If you want a 10,000 year old site, better find 10,000 year old dirt."

LOL.

I'm reminder of Al Goodyear (Topper Site). He said he stopped digging there when he hit the Clovis level. Only later did he decide to dig deeper. Guess what, he found more human mfg artifacts at the deeper level too.

The Clovis (Only) folks will say the gophers buried these things .
