This nice sample from the tonto national monument, arizona, is hard stone now, but it once was soft sediment, and it records formation and "fossilization" of mud cracks. the light was shining along the arrow, as shown, making shadows, some of which are indicated by the arrows. is this sample upside-down (you are looking at the side of this sample that was down when the sediment was soft) or right-side up (you are looking at the side of this sample that was up when the sediment was soft)?
