Swildon’s Sump 2, 21st November 2007
November 22nd, 2007What on earth could drag Marek out of his summer hibernation if not the prospect of watching an attempt Swildon’s Sump 2. The prospect of this 25 foot free dive hadn’t draw a big crowd, even while changing at the barn Trev was still undecided whether he’d join Dave and I through the sump or not.
There were a lot of cars parked at the barn and we wondered whether congestion in the cave would prevent us getting far enough in time. We had to wait a few minutes to enter as a large group were coming out and then we met a couple more along the ‘short dry way’. One of the pair had just done Sump 2 for the first time a few weeks previously and assured us that it was good. He said it just needed full commitment but it only took about 15 seconds. As we got to the 20 foot ladder we met another group doing the round trip and the large collection of ladders meant there were at least another 3 groups somewhere in the cave.
We arrived at Sump 1 to find it was completely covered with a thick layer of foam (as it so often does in high water). Trev and I decided here was as good a place as any to put on our neoprene balaclavas and face masks, Dave on the other hand was obviously made of sterner stuff as he didn’t have either (although he did zip up his second wetsuit). Marek on the other had was about as keen on going through the sump as he is on turning up for a dig night, so we agreed we’d be back in 30-45 minutes and the three of us popped though Sump 1.
After a few minutes in the stream just before Sump 2 my head light decided that it was no longer going to work and I had to switch to my emergency light (not ideal). We arrived at the bucket of lead weights at the entrance of Sump 2, whilst Dave and Trev already had diving weights (although to be fair Dave had only shoved his in the inside of his suit), I had a few bits of lead pipe strung together. I put on 4 weights (which was about as many as I could have got on my belt) and headed off.
We agreed a system of rope ‘tugs’ which went something along the lines of: 2 tugs means “I coming back”, 3 tugs means “next one though” and loads of tugs means “I’m panicking and coming back really fast”. I was the first to go through; I took a deep breath and as I sunk down I started to pull the rope through my hands. I’d put my face mask on although why I bothered I don’t know, the water is so muddy you can’t see anything; if you’d have dropped the rope you could have been in big trouble.
The guys we’d met said just take it steadily and don’t rush and after what only seemed like only a few pulls your head hits the part where the roof lowers (if you were pulling along too fast you’d get a fair whack). At this point you have to pull yourself down a foot or two to get under then end and then you immediately start to surface. I gave the signal and turned off my light to see if I could see Trev coming through. The water is so murky from the silt at the bottom of the stream way Trev’s light was just glow. Trev came though next, gave the signal to Dave who came through last. The passage between Sump 2 and Sump 3 is an echoey chamber where you stand chest deep in water. As we waded/swum off to Sump 3 there is a small duck just before the last chamber before it sumps again.
Sump 2 doesn’t seem to take long at all, much shorter than expected and I was half tempted to carry on and see what the third sump was like but decided to leave that for another day. On the return Dave went first, followed by Trev with me brining up the rear.
The return trip though the sump seems very different; from the initial dive down to pulling through the water you seem to be constantly knocking your head on the roof. This is probably due to the rope on the return being attached to the ceiling and you pull yourself up to it where as on the way through the rope goes under the end and you pull yourself downwards all the way. With a brief stop at the bucket to return the weights we headed back to Sump 1. A short pull though found us back in the frothy pool where Marek had been joined by a group of 3 cavers. One of them was a novice who was trying to decide whether he fancied going though the first sump or not.
As we all headed back to the 20 foot ladder we caught up with a group from Bristol University and as they left with their ladder we dropped down one of the 3 ladders still remaining. We got back to the barn about 10:20 and were in the pub by 10:35 where we found Sean at the bar – his ribs still a fair way off from caving. Reading the book over a pint we found that Sump 3 is only 10 foot longer than Sump 2 at 35 foot although it’s about 7-8 feet deep and at the bottom constricts to around 18 inches. Still as Sump 2 was much easier than we were expecting so we’ll have to put Sump 3 on the trip list for next time..!!!
