I've always wondered about the big rocks that one encounters at Mountain View Cemetery. I have asked the docents if they were placed there or if they are natural. No one seemed to know the answer and some speculated that they were put there, while others were fairly certain that they were natural.
Well the mystery may have been solved by Andrew Alden at Oakland Geology. Check out his fascinating post at http://oaklandgeology.wordpress.com/2008/04/17/knocker-on-display/
