Going back to the orange peel part of this thread, has anybody done a survey of this part of the cave?, as I dont find it mentioned on the Goatchurch survey I got a few weeks ago,because if not, on Wednesday this week I will be taking my kids up that way (got a day off school-learning review day) and I thought that We could have a go at doing a very rough survey of this passage.An interesting way of teaching maths. Got everything I need I think: Compass,long tape measure, and an angle measuring implement, (namely a protractor on a piece of wood), crude I know but it works.Flask full of Oxtail soup. (very important), cheap digicam for photo records. Just hope I can get into the passage and am not too big.
