"Sure, it looks a lot like a sinkhole," geologist Sam Bonis told Discovery
News from his home in Guatemala. "And a whale looks a lot like a fish, but
calling it one would be very misleading."
Instead, Bonis prefers the term "piping feature" -- a decidedly less sexy
label for the 100-foot deep, 66-foot wide circular chasm. But it's an
important distinction, he maintains, because "sinkholes" refer to areas
where bedrock is solid but has been eaten away by groundwater, forming a
geological Swiss cheese whose contours are nearly impossible to predict.
The situation beneath the country's capital is far different, and more
