I got completely lost in a mine the other day. A really expansive catacomb. i can't even remember now how i ended up getting lost. It has several "floors" with waterfalls making little islands below me in the massive lava pool. In the end, and luckily for me i'd bought some wood down with me, i crafted several pickaxes and simply mined upwards.
Breaking the surface and having the water flood in from the sea was pretty awesome.
I made a big ass mining complex in a coastal mountain in SMP, when I stumbled across a natural cave way deep underground. It was pretty big and expansive and it ran in to the direction of the sea. I, too, got lost, and I started to dig upwards. Then I went back in the cave, moved further, dug upwards, went back.. etc.
When I was done exploring, I connected all the 1x1 'skylight' mineshafts to my own man-made mine and the whole confusing cave was much easier to navigate in

The sea was littered with small cobblestone platforms with candles as well

Seafloor being 20 blocks beneath the surface, had to make cobblestone shafts underwater.
OT: My rage isn't the game, but the players. Once a griefer flooded and destroyed minor crap in my mine, which ticked me off. The second griefwave was much worse unfortunatly - water fucking everywhere, and he used my vast cobblestone supplies (I kept every cobblestone during the excavation of a 40x20xmanydigitshigh hall) to fill up the shafts I dug. Farm topside looted and demolished. Ugh, I hate people like that.
Moved away from that area :< And started somewhere much further away from the central spawn of the server I play on.
The rage caused by the game? Somehow my farm valley was on the highway of Creeper Convention. Turning around and seeing 4 of them closing in on you = not good. It was like that every night :<
