Nancy and I found these geologic wonders in a dry stream on our way to Bryce Canyon. What are they?

One of the beautiful parts of the landscape in Utah and Arizona is the way erosion shapes the land. Looking at the buttes and mesas, we can see that the entire area was once covered with quite a bit of rock. Most of it has eroded away, leaving the eroding buttes and mesas to tell the story. Is this a butte or a mesa?

Just looking at this boulder-strewn landscape can tell a geologist what kind of rock the boulders are made of, and how they got there. Can you tell the same thing?
