All the Way Down, Virgil the Turtle’s Greathouse Cave, Montana, United States

Seen in this photo, Elliot Stahl is struggling up a hill toward Virgil the Turtle’s Greathouse Cave, the second deepest limestone cave in the United States(and the 5th deepest US cave in general), which was discovered in 2005 by myself and Hans Bodenhamer, Jason Ballensky, and Ben Sainsbury. A 25 mile hike is required to access the cave, which is over a mile long currently and -1586 feet deep. It’s still being explored and at only 18 feet shy of being the deepest limestone cave in America, we hope that it will one day take the title.
