Day 81: Deeper and deeper

Day 81:

Hot day today so I went back underground, where I’m happy.

Found yet another vein of granite and diorite, this time a bit off the last one. They’re getting deeper, which means the temperature is actually starting to climb a bit. Still damp as anything though.

I’ve thought about starting fires underground to dry things out a bit, but one never knows when one might accidentally set a coal seam on fire, and that’s no good.

I’ve also thought about bringing one of the duckens down here on purpose to act as canaries. Make sure the air’s good. That kind of thing. That might be easier than the fires.

Watercolor of a blue background with a red, orange, and yellow sun superimposed on it, taking up the vast majority of the image. Instead of looking dramatically hot, it looks like a bad target.
This is supposed to be the sun beating down on me.
