I’m leading a discussion group using the videos from Haarsma’s Origins book. I was asked a question about carbon dating. When I attended the BioLogos conference last March I sat in on Gregg Davidson’s breakout session on carbon dating. I found the audio online, but I was wondering if anyone might know where to get some of the actual presentation pictures/charts. There were some great ones showing C14 levels from tree rings, and another showing levels from varves and how well they overlapped.
