So how do folks do Lamons Cave (AL)? No through trips, or have the beavers been run off and the spring entrance unsumped?

My wife wrote a trip report here http://thekrusechronicles.blogspot.com/

The sump was clear with a smooth roof and there was a spare air available but I stayed with two others who did not want to do it. We explored further downstream.

I would never...an al9/13 with a reg on a 3-6" hose takes up very little room.

People say that about caving in general.

no, id say that people say that about crossing a no vis sump on a breath hold 5 to 15 feet. But you already said you arent doing it, so you arent the darwin candidate.

No, I'd agree with Jeff. I've often been scolded by people for risking my life in caves.
I agree that diving a sump with a breath hold is an iffy idea, but I'm not real comfortable in the water anyway, so I may be a bit of a sissy.

No harm in being afraid of water filled passages.

I'm a cave diver (full cave certification) and even I think that free-diving a sump is madness.

I'm convinced now.

Yes, but how many cave diving accidents haven't ended in fatalities? I can think of 3. Ever.

Looking back on it, I wonder if those six attempts were dry cavers or cave divers?

Fully trained and equiped, would I dive through a sump? Sure.

But me, sitting there in just coveralls and kneepads, trying to hold my breath through a sump? I'll pass on that.

It may be interesting to look at the "Description" section on http://en.wikipedia.org/wiki/Swildon's_Hole. The "free divable" sumps are usually equipped with lines strong enough to pull on and Sump One played an important part in the History of UK Cave Diving.

Sump One proved to be very short: about 3 feet long, and is regularly free-dived most weekends.

I would also point out that the ACA is a bit bias in terms of its numbers, you don't read about all the successful sump dives.

That said, I rarely read this forum but the title caught my eye.

Unfortunately the only body recovery I've been involved in involved a free diver with a small pony bottle who got stuck in a hole after poking his head into check how much progress they had made moving some rocks from the entrance. He died within sight of his friends and his his waist and legs free.

So, I'm always a bit touchy when I read about people taking risks above and beyond the necessary or normal for the activity.

Yick. That's a bummer of a story. My condolences.
