The mysterious ledges of the Chasm-Canyon system.

Deep down the Chasm ( the famous part of the Canyon that has a very narrow top opening) is lit by sparse sunlight breaking through the narrow slit, and by the sidelights illuminating the Yellow Brick Road. The major feature in this picture is one of the ledges that are found all over the northern peninsula. These ledges protrude out of cave floors, mountain valleys. This part of the Chasm is over 800 feet deep, shows no traces of erosion or natural arch formations, and has no debri to suggest that the ledge was a part of an arch that collapsed.
