Game 38 Episode 1 (Round 27 Part 1) - Raving Island Ravine
Under Raving Island I explore the Ravine and the Caverns connected thereto. I realize at the end that the bottom of the Ravine reaches the Lava Ponds at y level 13 and so I can establish a Deep Mining Outpost there.
This video shows me using the common technique of placing Torches on the right when going into new Caverns and following Torches placed on my left going out. I also place torches in the middle of junctions. At junctions I usually explore the Cavern closest on the right first. Once a dead end is reached I mine all the Ores in that section of Caverns and mark the entrance with either a Gravel block (if there is a Gravel vein) or Dirt if no Ores or Gravel remain.
In this series there is no editing of the video and no commentary. I offer this as a Longplay format for a relaxing viewing experience. Except perhaps when a Creeper drops from the ceiling...once or twice...
