’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 concretions that are a bit harder than the encasing sandstone and were incorporated in the pinnacle. When they were eroded out of the surrounding stone, the marbles rolled down. NASA came to Utah to study the phenomenon. Photo Paul Smit.
