Descent 305 - Pre-order is open!!
Our August/September issue has a publication date of 2 August, and it is a special summer bumper issue full of stories of exploration and wonder from the underground world.
I have a scribbled note that you need at least 100m (but it does not have to be a singe rope) and 50 krabs to reach the tyrolean and maybe another short rope beyond. Better to do it with a rigger & a de rigger so then you can manage on a 40m +20 Krabs. Easier to walk back!
You don't need to rig the whole thing, you can rig out a number of bolts, and start derigging behind and then pass that end of the rope forwards when you have run out of rope IYSWIM
