We were amazed by how much the flow from the spring had dropped just since last week making us think that it won't be long and it will stop all together. We were able to survey another 200 ft of passageway before one of my hoses developed a leak and we had to turn the dive. The last time up my neck seal had leaked quite a bit, enough to make me wonder if I had leaks elsewhere in my suit, however, on this dive we took a little extra time to adjust the seal and that stopped the leak, however we were about 80 minutes in 40 degree water so even with drysuits working correctly we were still quite cold when we got out. This cave gets more fascinating as we go. Up to this dive the passages have been running on a very much northerly course, however the last 130 ft the passages are quite shallow and running just a little west of south making us think both passages are associated with the same N - S fault line with the deeper passages running north and the shallower running south. At Jim Wyatt's elbow the passage takes almost a 90 degree turn and is heading almost due west and there enters the Florida passage, that's as far as we made it before the hose started leaking. We now have enough information to start a good map of the system.
We exited the cave to find it snowing, big wet flakes about the size of quarters, that made breaking down and stowing our gear and getting out of our drysuits and into warm, dry clothes a whole new challenge.
We are hoping to be back up next weekend and place some line protectors in the high friction areas before the flow completely stops making it almost impossible to get back past Tibby's Table; hopefully the line will survive the high flow season next spring.
