Got tension in your life? See what happens when Mother Earth gets tense, up close and personal.
Crack in the Ground, in south central Oregon, was formed some 10,000 years ago when volcanoes erupted in the desolate Fort Rock Basin. Subsequent earthquakes put pressure on existing fault lines and the resulting tension ripped open long fissures in the ground. Virtually all of these fissures filled up with lava or caved in. At Crack-in-the-Ground, however, the gash is still open and stretches two miles long and up to 70 feet below the surface of the earth.
“Entering the crack is like entering another world,” says geologist Daniele McKay. “The path descends into a narrow slot between high rock walls, the desert dryness is replaced by cool moist air, and the sky becomes a narrow band of bright blue high above the chasm.”
