Found this cool rock at lake Tahoe. It has 2 white rings around it that are so perfect I thought at first they were drawn. Now it lives in my Chia pet garden. Here’s an additional pic.

In geology, a “fault” is a place where rock has broken apart and the parts have moved, so the two faces don’t match up any more.
This would actually be “jointing”, where it’s broken but there was no movement
TIL about the distinction.
