Figure a week from now I'll have my computer fixed enough to post pics of the antique marbles I'm digging up. It's been driving me nuts that I can't post pics. Anyhow the marble I dug up today in Borosalvy Canyon just outside of Trona,Ca is a 1" diameter hand made in Germany circa 1880s lattacino core marble. It's the first one I've found after digging every day since March of 2003.
