Geo-sites meme: 101 American Geo-Sites You’ve Gotta See

Callan Bentley from Mountain Beltway had the idea to list the 101 American Geo-Sites mentioned in Albert B. Dickas’ book and to mark those he has already visited. The whole thing became kind of popular in the geoblogosphere, and this KMZ by one of Callan’s readers allows to explore the 101 outcrops one definitely has to visit in the US. So now here’s my list, in bold the places I’ve visited (as you will see, there are far much still to be seen than I’ve already visited!):

  • Bayrischer Pfahl
  • Riffmuseum Gerstetten
  • Caves with speleothems in the Schwabian Alb

Of course, there are many many more to be mentioned. Any suggestion which sites to include in our list? See also this voting by the Heinz Sielmann Stiftung on Germany’s most beautiful natural wonder.
