caving

It might not be one of the best-known or most popular genres of the trade, but cave photography is an actual thing... and it’s not easy.

In the behind the scenes video above, Knoxville-based photographer Chris Higgins shows us just how much dedication, discipline and dirt it takes to get incredible photographs of the mysterious worlds hidden within the Earth.

Consider this your terrifying action cam video of the week... or year. In a nightmarish four-minute video uploaded earlier this year, a man gets stuck in a narrow part of a cave while trying to get out. And as if being stuck isn't horrifying enough when you're under ground, it seems the cave is also filling with water.
