Isolated limestone mesa around 100 feet above Beaver Creek. In this mesa
is a huge open depression or crater about 600 feet across. Of great depth
in which clear fresh water stands at all times about 75 feet above stream.
There is a small opening through wall at one side from which a constant
stream flows into Beaver Creek. Lake always stands at same level. Water
is used to irrigate adjacent fields. In the walls are a number of cliff
dwellings. About 1884 a crazy man took up his abode in these caves. Was
finally captured and placed in an asylum.
