On the image

Somebody wired this cave for theater. By the 1960s almost every commercial cavern in America had traded its lantern-light mystery for a switchboard of colored floodlights, on the theory that limestone dripping for ten thousand years needed a little help from General Electric.

The historian's note

Commercial "show caves" proliferated across the United States and Europe from the 1930s through the 1960s, as improved electric lighting and highway tourism made underground formations accessible to paying visitors. Operators routinely installed colored floodlights to dramatize stalactites, flowstone, and drapery formations, a practice standard to the industry by mid-century and often criticized later by geologists for altering the natural appearance and even the mineral chemistry of the rock. Guided tours followed fixed walkways and scripted narration, with formations given fanciful names to hold visitor interest.

The specific cave shown here has not been identified by name, but the lighting rig, drapery-style flowstone, and framing are consistent with a mid-twentieth-century commercial tour cave rather than a scientific survey or wild-cave expedition.
