Ed– >> Agreed with most of your post, but I understood the collision BEGAN at this time or a little earlier and progressed southward…the bulk of the continental collision occurred even later, in the early Permian. Am I way off base here? << Sounds like you know more about it than I do, Ed. I was just briefly trying to simplify things for Kamron, and generalized (always dangerous!), using some diagrams in _Plate Tectonics and Crustal Evolution_ by Kent C. Condie (1976), which show North America and NW Africa scrunched together in Devonian, and spreading apart in Triassic. Thanks for the clarification (I'm a Rocky Mountain boy, and treading on dangerously thin ice when I talk about eastern NA!). Howard
