    That's awe-inspiring work.

    My sole plan to enhance my cave diving knowledge involves going to listen to a talk by Martin Farr in a welsh pub next month. I therefore take my hat off to you.

    In particular, I admire your achievement in including not one, but two, crudely drawn penises...

    The Salle de Lavaur is as far as I have been in St Georges (only 3 dives there) and it is very impressive. I would never have said the ceiling goes to 50m!
    Excellent work.

    It's very deceptive, with no visual references for scale. The bit over the lake is about 20m, but the aven behind is much higher. We were genuinely stunned when the disto said 60m+ (not vertical).

    Shape looks like this :

    Awesome. I look forward to diving there again, but I will never see that for myself. You brave folk have different DNA I think! Quite brilliant mate.

    I have a few prints left in the batch if anyone still wants one.

    Details :

    https://dl.dropboxusercontent.com/s/..._v1.3.pdf?dl=0

    I am just about to arrange a short print run of the latest survey (v1.3).

    At 1:1000, it is 17" x 68" (43cm x 173cm) and will be printed in colour on decent quality 200gsm paper.

    The print cost will be 10 each. Postage and packing in a tube to wherever you are at cost (4 UK) or we arrange some kind of collection.

    If anyone would like a copy please let me know asap.

    Steve

    We have made some updates to the survey. This update is based on data collected in August 2017 by a team of 4 rebreather divers. The main updates include a survey of the dry section between sump 2 and sump 3, improved detail on the sidewalls & sections in the deep section of sump 2 and a correction of a previous depth errror at p.1050m.

    Survey (v.1.4) is available here :

    A really good achievement by all you guys.

    The only other survey I've seen that's any good beyond deep sumps is Marcus' survey up to S6 ressel.

    I genuinely find it very impressive!

    However, I think your scale is breaking down a bit between S2-3. I really don't remember those rifts being 1m wide! :P

    I’ve not really drawn any cross-sections in the narrow bit (the last 100m before sump 3.) It is quite narrow at water level and the walking route is higher up. I’ve not got a sketch of it, but may be able to create it from the video.

    One of the challenges with drawing a 2D survey is chosing a height in the passage to draw the plan at. This is much worse in the 45deg diagonal awkward areas. The cave may be 8m wide and 8m high, but you have to squeeze through. I’ve generally chosen the typical level for swimming/walking. Swimming/Line level underwater and walking level in the dry.

    I was just being annoying! If you actually drew it at 1:1000 scale it would just be a line from my memory!

    Mostly, amazing achievement!
