fourth photo of the fourth folder

Originally uploaded by Jurassic2008

Greetingarts.typepad.com issued a challenge to blog and describe the fourth photo of the fourth folder on my computer. While she had a cute photo of her little girl (my niece), I had a very different photo!

This is a block of serpentine rock which is also a good example of “slickenslides” which is the shiny, “scratched” surface which is created by geologic forces. When two rock faces are pushed against each other, the pressure alters the minerals slightly.

Fine print: photo was taken in April 2008 from McLaren Park in San Francisco. It was a block which had been moved and placed around the pond so it was not in place. (As a geologist, I feel obligated to state that!)
