In an act approved on March 26, 1948, the legislature protected privately owned caves exhibited to the public. It prohibited "the destroying, breaking, tearing down, writing upon, marring, handling or carrying away of any rock, wall, or other formation" within such caves. Offenses were to be punished by a fine of not less than five dollars or more than one hundred dollars or by imprisonment of not less than five nor more than thirty days.
