So Cal caves?

[JonKranhouse]

Are there, in fact, any diveable caves in Southern California that aren't sea caves? My guess is that the branching network caves we think of in limestone aren't available much there.

AFAIK, the only limestone caves in California are thousands of feet above sea level. in the SoCal desert there's Mitchell Caverns. Mid-state, in the Sierras, is Crystal Cave (Sequoia Nat'l park) and Boyden Cave (Kings Canyon). There's probably yet-to-be-discovered sections in these that are flooded.
