Hello to you, dear reader.
This summer, I am reading the exciting and well researched book "Early Human Life on the Southeastern Coastal Plain" edited by Albert C. Goodyear and Christopher R. Moore (Link). Chapter 2 of this book describes in depth all the archaeological levels of the Topper site including the layers that have been dated to well before the Clovis period. I'll have more to say when I'm finished reading.
Wishing you an enjoyable summer.
