You need to add a couple to your total. There were 2 rescued in Marianna, FL a couple weeks ago. Before that, 1 in Thunder Hole, 2 in Otter Spring, 1 in Bat Colon cave. Did I miss any?

2 friends and I dove a sump 4' long 3 years ago. Never again. No one died but the thought of going back once we got in was horrifying

With some sumps it may be best to come back during an extremely dry time and check it again. Maybe then it will not be a sump.
It only takes one person to surrender a dog to a kill shelter ,but it takes many to rescue it.

I have seen a few in Indiana and Kentucky that were seasonal.

i take that back. a paleo segment of oru river cave survey floods upon retarded storm drainage and sumps out. It takes a few months for the water to perculate through the clay to lower levels/or evaporate, however it gets out. During those times its sumped out but this is 20=25 feet above the stream. The stream level sumps do not drain out no matter how long it doesnt rain.

I broke through a sump in Tennessee, and a few hundred feet later, it sumped again. I had left my gear at the first sump, so I didn't even look at the second sump. A few months later, TN had a serious drought, and some "dry" cavers crawled through both sumps. Then they found a place where the cave came very near the surface, and dug a new entrance. They mapped about two miles of cave. Cave that I could have been the first to go in, if not for the drought :doh:

Actually, we've mapped over 5 miles of "new" cave and then we also dug a connection to a cave we had mapped 4+ miles in years ago and the total to date is over 10 miles now. When we pushed it, the first sump had about 3" of air space and the second was just a mud waller. About 1500' into the new stuff past the sump we had to pop a rock to get through to the rest.

Sounds like the same cave. I guess I need to go look at it again :roll:

If you want to go in the dry way, holler at me or Marbry when you're up this way.

Just to add my point of view to this from the UK. The third trip i ever did in a cave was to swildons sump 1 a 4-5ft sump, which i did without problems. The fixed line in the sump makes passage through it much quicker than swimming as you can drag yourself along. but the shape of the passage is important as well as the length, i would do longer in open passage but anything smaller i wouldent do an inch. be carefull out there
