AN ARCH IN THE MAKING?
Is this An Arch in the making? A cave develops in side of a rock
fin. The cave is enlarged by continuing WEATHERING and EROSION.
Eventually the cave enlarges through to the other side of the
fin and an arch develops. Or maybe the roof caves in and there
is no arch. Nature will decide!
Images L58 thru' L62 are in sequence and should be viewed as a series
