Sandstone secrets

Walking on dirt roads is a bit more difficult than paved, of course, because of all the loose stones, but it's also more interesting... because of all the loose stones. My favorite thing is finding broken ones. The sandstone especially will look completely boring on the outside of the rock: smooth, dirt-colored. But if you find one that has a fresh chip, you can see the patterns inside. Sometimes they're striped--red and brown, purple and white, yellow and orange. Those stripes are physical history from such a long time ago. It gives me chills.
