Cosmic Airbursts – Impacts Leave High Temperature Melt Products at Younger Dryas by George Howard
I discovered a rogue PDF of a 2006 text I have long coveted. It was just as good as expected. Chapter 2.3 is a fascinating summary of the Bruce Masse myth studies, among other goodies, and taught me a thing or two.
Cheers to editors Peter Bobrowsky and Hans Rickman:

Newton’s Great Comet of 1680
Update: A couple of useful links and a popular article on the subject.
I just learned of the discovery of Comet ISON which has apparently electrified the astronomy world for months. What then caught my eye was a paper from David Eichler of Ben Gurion University published just […]

I am not surprised. This is an absolutely fascinating subject and […]
These scientists have identified three contemporaneous levels more than 12,000 years ago, on two continents yielding siliceous scoria-like objects (SLO’s),” said H. Richard Lane, program director of National Science Foundation’s Division of Earth Sciences, which funded the research. “SLO’s are indicative of high-energy cosmic airbursts/impacts, bolstering the contention that these events induced […]
