The Bob has a deep, dark wilderness secret
PUBLIC LANDS -- As many times as I've been into the Bob Marshall Wilderness in my home state of Montana, I've never explored this deep, dark, wilderness secret.
The Missoula Independent reports that Tears of the Turtle, the deepest known cave in the continental United States, is protected from being too popular among spelunkers because to reach it one must trek 22 miles through the Bob Marshall Wilderness Area.
The deepest known point of the cave is 1,629 feet below the surface.
