Tips for not getting lost underground?
Today I discovered a very big cave (I explored it for like hours and it still has a lot of places I have to visit) but suddenly I decided to go back home. I was expecting I would have some troubles finding my way home, but it took a very long time to try to go back to the entering of the cave. After several minutes of walking circularly I decided to just dig up until I saw the sky.
Now, I had a method to orientate my self toward the exit (using the direction of the torches I placed down there to indicate a previous torch or the exit) but it didn't have any success.
I think of creating a bunch (something like 12 x 64) of signs and start writing directions but I was wondering: is it really an option? would you suggest it? are there any other way to orient are yourself down in caves?
Thanks.
