Hey kids, The wife and I recently started rock hounding. There's a problem though, neither one of us really know what to look for outside of finding "neat" rocks. I'm fairly certain I'd know gold or silver if I saw it, but anything else I'd probably miss. Does anyone know of a good online resource for identifying minerals and gems, or rock hounding? We did find some petrified wood the first time we went out, so that's a start, right?
