| Mysterious Rock, Puget Sound |
I have not posted for quite sometime, not having had much time - or weather - for rockhounding. But every chance I get to walk on the beaches below my house, I typically find something. In this case, a few weeks ago, I spotted this interesting cobble (about 2" long) and threw it in the tumbler. The polish revealed a fascinating pattern which I can't identify or explain. Any ideas? A kind of agate?
