Frogs and fossils and old fashioned cell phones

Today we went to Sunol Regional Wilderness and these are some of the things my camera saw:

That's a fossil that we found. Those are sea shells from some sea that was here some millions of years ago. I still think it's amazing that we found it.

The hills are green there but won't be for long. If you are looking to go somewhere outside that feels a world away, Sunol is it.
