In tribute to the massive sink hole that opened up in Guatemala earlier this week, we give you 3 other fascinating earthly swallows. Why the interest in morose geological phenomena? How could you not be intrigued by spontaneous circles giving way to earth's fragility, uncovering the mysteries of our core? The Great Blue Hole served as a treasure trove for Jacques Cousteau, the perfect holes of Sarisarinama have perplexed scientists for centuries, and The Devil's Sinkhole in Texas was revered as sacred grounds to local Native Americans.
