(Alum Cave isn’t really a cave, it is a bluff. A bluff is a rock/cliff face that leans outwards, which is why the folks that named it used the word cave.)
The various, abundant life is not the only reason most mountain trails are beautiful. As many trees there is, there are an equal amount (if not more) fallen and cracked trees/stumps.
These fallen trees make homes for wildlife and plants alike. It will dissolve into the ground from which it came, and the cycle continues.
The journey up any mountain is amazing, but all the little details we walk by are just as interesting.
