Coming to a city near you: Weird/terrifying holes, Part II
Sunday, December 15, 2013, 6:55 PM
A few weeks ago, having noticed our readers' apparent love for stories about sinkholes, we put up a weekend feature listing seven notable weird/awesome/terrifying holes around the world. It turned out to be the most popular weekend feature we've ever done.
We get the message, so here you go: Seven MORE weird/awesome/terrifying holes, from giant underground caverns, to man-sized crystals, to glimmering, colourful pools.
Every now and then, a giant sinkhole swallows part of a Texas town
We led off our previous installment of this semi-series with the Bayou Corne sinkhole in Louisiana, where a ruptured underground salt dome was slowly devouring bits of swampland.
Here’s what it looks like when that happens on dry land:
That’s the ragged edge of a 45 m deep and 182 m wide sinkhole that was apparently once a wooded field. The United States Geological Survey says it likely happened when a rapid injection of fluids caused part of the 10-km subterranean salt dome to to dissolve (other sources blame erosion at the top of the dome).
In 2008 when it first opened up, it was a terrifying experience for everyone involved as it swallowed several vehicles and structures and sent the small Texas town of Daisetta into a panic.
Five years later … looks like everyone has learned to live with it. This source notes one couple who saw the hole open up not far from the foundations of their under-construction abode ended up finishing the home a year and a half later. A nearby highway whose surface dropped 10 cm was reopened several months later.
As for the sinkhole itself, it’s just a salty pool now.
It seems two similar holes opened up in previous decades, so we guess the good people of Daisetta are probably just getting used to it.
