Recumbent Fold in San Pedro

Layers of sediment compressed on the ocean floor for hundreds of thousands of years become sedimentary rock. Here the rock has been slowly deformed by the earth's forces of pressure and heat from horizontal to vertical, hence older rocks are positioned over younger rocks. This is known as a recumbent fold. (Located at Royal Palms State Beach).


  1. Nice geography/geology lesson and great photo!

  2. A good friend recently gave me a lesson on this very kind of rock formation - or deformation, if you will.

  3. oh wow, that is so cool! what a great lesson too. thanks.

  4. That's what I call beautiful science.
