BLACK CHASM CAVERN Guided walk tours available every day of the year. The venue is located about 2 1/2 hours from Sunnyvale area. Black Chasm Cavern was designated a National Natural Landmark by the National Park Service in 1976 after being recommended by local members of the National Speleological Society, and as such is considered a "nationally significant natural area.? Visitors to the cave are enchanted by the beauty of a wide variety of formations including stalactites, stalagmites, flowstones and the vast arrays of rare helictite crystals, for which Black Chasm Cavern is justly famous. Above ground, kids love our gemstone mining at our mining flumes right outside the Visitors Center. Everyone is guaranteed to find some real gemstones; the perfect start to a rock collection! Try our new incredibly popular geode cracking too!

Hey all.. I figure we all live close to SF but rarely do we ever get to do the "touristy" thing. So why not check out SF the way most of the world does. :)

Hey all, I would love to take a roadtrip down to Sacramento and either hit up Thunder Valley or Jackson Rancheria. Let me know if you'd like to join me. :)

I've always wanted to experience this. Currently in the process of researching a local venue -if anyone has any contacts, let me know. If you'd like to join me and think I should make this a meetup event, then select yes and where! Thanks! Lachmin
