Stumbled upon a loving massive (really, it's absolutely huge) network of caves during some excavation. After flipping it to peaceful to get some serious exploration done, I wandered through it for probably two hours and still haven't reached every extent of it. It's amazingly confusing but so mineral rich. I've got more iron than I know what to do with and I'm stumbling over a decent amount of gold. Unfortunately, I haven't seen the light of Minecraft day in a very long time and it's starting to spook me out. I keep thinking I'm going to get so deep in this thing I won't be able to find my way out D:
