Steve, Thanks for the info on Ohio geology. In a way, the features must be more dramatic since they are unexpected. The one John McPhee book I haven't read yet is "Crossing the Craton" - which is about basically everything in between Pennsylvania and the Rocky Mountains - but along I-80.
You mentioned the Canadian Shield and now I am dying to go walk on that oldest exposed rock. Bit far though... And thanks for this picture that shows some geology in your region. The trip you all took is inspiring and your detailed descriptions help to decipher what's going on.
