<p>My son recently got a <a href="http://geology.com/rock-tumbler/" rel="nofollow">rock tumbler</a> and I was wondering if anybody knows of any resources that would show pictures of the different types of rocks as they would be found on the ground. I live in Chino Hills CA and we have many trails. I wanted to be able to tell the difference between something worth tumbling and something that isn't. </p>
