9402 thumbnail picture
Layers of resistant porcellanite rock interleaved with less resistant chalk that forms the eroded recesses. In this area, silt has sifted down from above covering many of the individual ledges formed by the differential erosion of the two rock types.

9403 thumbnail picture
Layers of resistant porcellanite rock interleaved with less resistant chalk that forms the eroded recesses. In this area, silt has sifted down from above covering many of the individual ledges formed by the differential erosion of the two rock types. Eventually the protruding layers will fail by slab failure eating away at the canyon walls.
