The polished rock face above my wife, posing for scale purposes in a slot canyon, is an example of slickenside, a deformation caused by the movement of rocks against each other in a fault. The smooth surface usually shows marks that indicate the direction of movement; in this case, the movement was vertical. Note the smaller section of slickenside just to the right of my wife's knees.
