This partially answers the question of how AiG-US will conduct future "scientific" work, a question which CMI had raised since the Australians were the main contributors to such AiG efforts in the past.
A question that hasn't been answered is why Snelling stopped working for Creation Ministries International and went to the ICR. The Briese report contains this tantalizing tidbit of information, which I haven't seen anyone publicly comment on to date:
I clearly remember him saying that Andrew Snelling [a former Australian staff member who was opposed to the notion that a Christian can ever remarry. He was later dismissed by the Australian Board, which at the time included Ken Ham, for matters unconnected to this issue.] had been right about it at the time and that he (Ken) and others had been wrong. But Ken didn't give me any convincing reason as to why he now saw things so differently and why it was now necessary to make an issue of it.This description makes it sound like Snelling's departure from CMI was not voluntary, and that he had issues with Carl Wieland (a Christian who divorced and remarried).
Snelling is one of the very few young earth creationist geologists on the planet with a Ph.D. from a mainstream academic institution (Steve Austin of the Institute for Creation Research is another). Ronald Numbers' book, The Creationists, describes how Henry Morris of the ICR wanted to see a young creationist successfully obtain a Ph.D. in geology from a mainstream institution, only to be faced with failures by Clifford Burdick (who was kicked out of the program at the University of Arizona) and Nicolaas Rupke (who succeeded in obtaining his Ph.D., but rejected young-earth creationism as a result of what he learned in the process).
