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.

    Yeah, but that looks more like a port on a plasma flux multiplexer that failed. You can tell by the rings. The coaxial field generator must have overheated, causing a loss of alignment. They probably didn’t have access to a source of clean iridium and just tried to make do.
