Day 798: hot rock

Day 798:

One of the crazy parts of this Swiss-cheese planetesimal is that any given time I can dig into what seems like a perfectly solid chunk of wall and discover that there’s a sinkhole or ravine or cave on the other side. Today I dug into the side of a mountain and discovered an open pit with hot-and-cold running liquids. (In this case, a water spring on one side and a lava spring on the other.)

The spring will be annoying because I don’t like being soaked in cold water.

The lava spring will kill me if I don’t do something about it.

So add those to the to-do list I would keep if I didn’t value my handmade paper too much.

Looking into a hole in a cliffside, there's a lava spring at the back of the hole.
