I just tried to pull up the web side listed in the Cosmic Catastrophes book. It is listed as www.cosmiccatastrophes.com, and it does NOT work.

I did find another listing referenced on the Googles page which does have interesting info: http://www.perigeezero.org/treatise/index.html

For those who are aware of the hypothesis that Lake Michigan was formed by two boloid strikes, they had a great underwater map. When I read the book it looked to me as if there could have been a smaller strike between the two larger ones, and lo and behold, there on the map is a third smaller depression between the two larger ones. I tried to transfer the map here, but that was beyond my computer skills. Someone else want to try?

I found it interesting Hawaii volcanoes emit massive amounts of iridium suggesting a mantle piercing impact.

Yeah, that didn’t work for me either (the listed website).
