Yellowstone National Park, Part 1: island park caldera

» led2 - island park caldera

I live summers in the penultimate caldera -- our home is 30 miles southwest of West Yellowstone.
Habiger's article is terrific -- gives a great overview of this area -- but many questions remain.
My current favorites are: what happened to the north rim? Is Henry's Lake within the IP caldera? Is West Yellowstone within either caldera, or is it outside both?
All this on top of "I'm unclear on the chronology -- is it "eruption, tectonic movement, fault thrust (creating surrounding mountain peaks), glacier"?
Thanks for all info.
