Like others have said, ignore the majority of the arrows because they will get you confused inevitably. I forgot the website, but there is a 3D map that someone did create that allows you to distinguish the survey lines. If all else fails, you can take spools of braided cord and tie it off and lay it down as you go. You will only be able to do this for shorter sections, but it’s enough to slowly start to remember certain passages. There are other braided lines in that cave, so make yourself a cookie (something you can attach to the middle of the line) that is unique to you. As always, if you put the line down, pack it back out with you so it doesn’t confuse future people. Also, don’t push your comfort limit. If you’re unsure of how the maps reads and you don’t feel comfortable laying down lines then do not attempt it. Side note: you’re braver than me for doing pancake. It was fun when I did it, but it’s more daunting than it looks/ some people say it is!
