It’s huge. Historically important. Geologically fascinating. Also somehow kind of boring. The same features that make it the longest cave system in the world also make large sections of it look like somebody hollowed out a government parking garage underground. There are cave systems in Appalachia that look like fantasy novels. Mammoth often looks like an unfinished subway tunnel.
And yes, I know this is partly because I’m comparing it against non-tourist caves where you spend twelve hours crawling through mud and regretting every life choice that led you there. But still.
At least Carlsbad Caverns has drama. Giant chambers, formations, actual spectacle. Mammoth Cave feels educational in the exact same way a limestone textbook would feel educational.
