I don't really think so. I did a bit at first. But I researched this last night. My friend, who owns the land told me that this type stone is glacier sediment, and it just breaks like that. The smooth oval , does look like an eye from one of the Olmec statues and if you look again, you may be able to see the bridge of a nose and cheek as I did, but waste no time on it. In fact, I feel foolish. Then again, not really, if one doesn't dare see those things, he'll never find them.
