A series of Questions for our Geologists.

The Arbuckle Mountains between Ardmore and Sulphur, Oklahoma are a fantastic example of a fold with the middle eroded out. At the center of the structure you have Cambrian (or Precambrian?) stromatolites and such, and as you travel north or south you cross outcrops of practically every oil-producing formation in the state. Th fully "reconstructed" fold would supposedly be nine miles high, but of course it actually eroded as it bent up.http://www.geog.unt.edu/...frame_files/FIELDTRIPS/ok/ok.html
