Ok. This is kinda freaky.
MercuryNews.com: Authorities on Saturday were investigating an odd discovery on National Park Service land near San Francisco. About 1 p.m., a park visitor found the remains of two human skulls near the Sutro Baths, a part of the Golden Gate National Recreation Area just north of Ocean Beach.
The remains were found down a steep cliff, U.S. Park Police said, and may have washed up from the ocean.
