We were there July 28-August 12, and it was open the first day we were there, then closed for about 1 week, they covered the "problem area" with a camouflage type of thing, I was told by a CM that lightning hit the mountain, and it was unstable, not sure if it is true, it did look like there was a huge hole, the problem area is right after the cave where you cross the lazy river on the bridge.
