Stock Creek spent a million years dissolving a passage clean through a limestone ridge, leaving a cave more than eight hundred feet long and tall enough that a railroad was laid through it in 1890 rather than around. William Jennings Bryan called it the eighth wonder of the world and the name stuck locally. Coal trains still run the bore, and a chairlift drops visitors to the floor of the gorge to watch.
That was 1 of the hidden places.
