The Tusk recommends the blog Crater Hunter: A Catastrophe of Comets as another stop to study strange claims and the science that supports them. I think it is authored by Dennis Cox(?), but regardless, the author is clearly a brave and dedicated soul — and the writing ain’t half bad.
The more I learn about “ ignimbrites,” to this blog as Carolina bays are to the Tusk, the more I am persuaded that no one knows for certain what the hell caused them and they deserve an explanation. Looking forward to leaning more from CH.
