A lifelong friend and I are at the mouth of the cave, about to embark on a guided tour with a naturalist. Along with people we never met before, we’re entering Mystery Cave near Preston, Minnesota.
Before this moment several years ago, we had studied the history and geological displays in the nearby welcome center. I was in awe when I discovered the cave expanded for miles, stretching underneath farm fields through the limestone landscape. Without the signs, maps and indicators elsewhere, I never would have known about the expansiveness hidden away beneath the surface of Earth.
It is the same with humans: Much of what is hidden below the surface is often unknown, unmarked.
I am not surprised to feel the chill of dampness upon my skin once we cross the threshold, as we make our way forward into the dark. What I am surprised by, however, is how the space feels like a cathedral. A sanctuary. The giant stalagmites and stalactites seem like the pillars ascending and descending I’d find in church.
