Old Postcards: Mammoth Cave





The color photo of the historic entrance reads on the back, "The old historic entrance to Mammoth Cave is the only natural entrance. It was discovered in 1799. There are also five artificial entrances."

The black and white card is actually postdated 1907!!! It is over a century old.
