Photograph from the rear of the cave looking out.
Cave goes back about 30 feet.

Ceiling height decreases inside to about 4-5 feet,
then rises sharply to about 10 feet in the rear.

The Mount Jefferson Cave could be more accurately defined
as a Crepuscular Cave or Twilight Cave as it's
inner cavity is not in total darkness.

There are also several Alcoves and Rock Shelters on Mount Jefferson.
