The safety bottles are back in Indian, and it is open for diving.

Keith Mille and I were in last Weds, and the visibility is as follows:

Basin - 6-10 feet
Cavern - 30-40 feet
Mud tunnel - wall to wall
Downstream - 100 feet plus.

I have a similar report from upstream, Jason put the bottles in there.

Indian is about as good as it gets. Requirements are 100 logged dives after full cave, tri mix, DAN insurance - Roughly the same as Emerald.
