My digging has brought me back to the ravine, and for some reason the skeletons zombies are still congregating there. I even saw a “kid” zombie with a shovel! If he had been on my side of the ravine, I’d have an extra shovel.
I’m not likely to find diamonds sticking straight out of the ground, here, so I’ve given myself permission to get past it as fast as I can. Unfortunately that still means clearing a lot of stone and rubble going down.
It’s tempting to use that rubble to fill up the ravine, but then when I get down there I’ll have to dig through my own rubble to check for diamonds, and that’s annoying.
