Schultz has replied to Melosh several times, and will do so again. Schultz et al have conducted several more field expeditions to Rio Cuarto, with further analysis of samples. The Maya were quite specific about what hit - "GI", "GII", "GIII", and where it hit - "Matawil". You can add another comet sample to the list. See "Man and Impact in the Americas" for a full presentation - though the resultant climate collapse at 2360 BCE as shown by tree rings came in too late for inclusion in my book. I left out Canyon de Cielo at 2325 BCE, which also hit at "Matawil". What this Multi-National Geographic piece is is more crappy impact science by PR, the kind I've come to expect from NASA. Its nice to see NASA finally admitting to tangential impacts though. Change comes slowly. I wonder what year NASA will start to feature tangential impacts identified as such in either the MGS or MOd pictures of the week. good hunting, Ed --- "G.
