I found a spear in Golden Gate Park!

Yes, you read that correctly; I found a spear -- or, to be more specific, a rocky spear point -- in the park not too long ago, while running through the park on a rare, sunny day. GGP -- long before it was turned into a pleasure garden -- was just one more section of scrubby plants and sand dunes marching out toward the Pacific Ocean. Human habitation has a long history in what is now San Francisco -- reaching back to at least 3,000 years B.C. But this doesn't (necessarily) mean that the relic that I found -- and duly turned over to the de Young Museum, which transferred the item to the California Academy of Sciences, after I provided specific coordinates of where I found this 'surface relic -- is the real deal. Sometimes it takes careful examination to determine whether something like this is authentic or merely a discarded tsoschke from a gift shop somewhere. Stay tuned to this blog --- and I'll give you more answers within the week.
