so one day, while I was playing on a server, this guy asked me too follow him, so I did. he jumped into a waterfall, so I followed. there was a giant tunnel inside, and we both went in. He kept lighting the place up, and I trailed inside. after just a short time, we found a dungeon, which he quickly lit up. he took most of the items, and put a 64 stack of sand inside, which I took out. after a short ways, we found ourselves an abandoned mineshaft. as we explored that, we found multiple cave spider spawners, and a couple more dungeons. we both got about a 64 stack of both coal and iron ore. we cleared much of the rails and and wood, and continued through it. after a while of fruitful exploring, we both noticed out hunger and health and headed home. we both go monster hunting together often, and sometimes explore that ravine together again.
