'Marbles of sandstone.'
These marbles of sandstone on the plateau above the Paria Canyon are the same things as the blueberries found on Mars. They are a bit harder then the surrounding sandstone and were incorporated in the pinacle. While eroding, the marbles roll down. NASA came to Utah to study the phenomenon.
