Figure 14. Undulatory features similar to that in Figure 13 are seen in the center of the outcrop in the siltstone just to the left of the pick hammer point, and in the siltstone farthest to the left. This sequence of bedded metamorphic siltstone and sandstone layers, originally deposited horizontally, is now on end. The siltstone units have been eroded in this outcrop and as in Figure 13, the undulatory surface may represent ripple marks or slump folds. If so, it would suggest the tops of the beds are to the left in the photo.
