Larry Bleiberg from
USA Today asked my help in designing a list of 10 great places to see geology in action and I was quite thrilled to participate. The article appears in the
travel section of this weekend's edition. I had to think pretty fast, and we came up with the list that appears below.
Grand Canyon (above)
Death Valley (below)
Hawaii Volcanoes National Park
Yellowstone National Park
Dry Tortugas National Park, Florida, and Mammoth Cave, Kentucky
(for the coral reefs, past and present; but I don't have pictures)
Mount St. Helens National Volcanic Monument
San Andreas Fault, California (Carrizo Plains and Point Reyes)

Jasper National Park, Alberta, Canada

Great Smoky Mountains National Park (no picture for this one either...)
I'm wondering what places you would have mentioned...
