and I reread Robert Heinlein's The Past Through Tomorrow, a series of short stories from the 1930s through the 1950s that covers an alternate history.

In the stories that take place on the moon, Heinlein has the main habitation in lava tubes and lava bubbles, with additional living space dug below and to the sides of those tubes.

It's amazing what possibilities that he saw in the future!
