"Catal Huyuk in Turkey was abandoned by 5600 BC."
I have often wondered what impact the explosion of Mt. Mazama (Crater Lake) around that time had on the civilizing world. I did not know that Catal Huyuk was abandoned at what may have been the time of the eruption. I am not so hot at math [maybe someone can help out here] but if Pinitubo left a 3 mile diameter crater, and Mazama left a 6 mile diameter crater, then Mazama could have ejected around 16 times what Pinitubo did, when it caused our 500 year Mississippi flood and other severe weather in the following years.
Some years ago I saw and interesting article in "The National Geographic" about the excavation of a 50 foot high mound in Bulgaria. The pottery from 6,000 BC was bright and varied, and artistically interesting. Later pottery from 3,000 BC was dark and dull, although well shaped. At the time I wondered, what happened to the earlier people to bring about such a change. This was before I learned so many interesting things that could have had an influence. I wish I knew the date on that article, as I have a large collection of National Geographics, organized by year.
Regarding the round civic building, I wonder how similar they are to the round buildings found on Malta? Also, having discovered the book by Gloria Farley, "In Plain Sight" about prehistoric overseas visitors to the Americans, I wonder if there could be some influence on the round Kivas of the southwest Indians.

Take a look at the July 1980 issue
