Thanks for answering that, Realmsire! Yes, some of the maps have sections below what's immediately visible in the preview Page image as well as when you load the page so when you check the "keyed locations" make sure to zoom out or scroll down. If y'all don't mind my getting a bit geo-nerd in here, caves can be amazingly intricate and honestly? bizarre af. It depends on... a lot of things, lol. For instance kettle lakes formed from glacial retreats could be great for keeping tunnels below dry or mostly dry. All of that to say that the setup for the tunnels and water levels isn't actually impossible. But to stop myself from launching into further rambling mode about some of my favourite IRL caves, it may help to remember that Camp Clearwater isn't necessarily bound to the limits of real world physics, chemistry, and geology. The Keyed Locations handout does indicate where the tunnels are connected in game (for example sections 12 and 16b drop onto 17 and 20 respectively), if that helps at all!
