We have highs of mid 30s and lows down to -10.
Stone is an incredibly efficient thermal material which is why animals and humans have lived in caves for thousands of years.

Most stone makes for a pretty bad insulator. But the ground, in aggregate, is a great insulator and has very very large thermal mass. So you can go in a hole that’s more than a few feet underground, and the temperature is fairly constant.
