If I recall my Geology classes correctly, there is a very non-zero chance
that pretty much all of Yellowstone National Park could collapse into a
giant caldera within our great-grand-childrens' lifetimes.
These collapses have occurred periodically throughout geologic history....
the remnants of one of those collapses is now Craters of the Moon National
Park in Idaho.
I believe that a similar event is also responsible for having produced
massive floods that once destroyed most of the Eastern half of Washington
State.
