Tooth of Time

To the western breaks. Our aim was to look for green agatized wood, but we hiked all over the place.

There were fragments of bone scattered through the arroyos—even part of a jaw, you could see the tooth sockets. At the base of the cliffs I spotted broken antlers, picked them up…and they were stone. I examined them with a hand lens and found, on one, the tiny, parallel, transverse scars left by the incisors of a Pliocene mouse or vole.

Those delicate tooth marks are slightly over two million years old.
