Henderson County Sinkhole Leads to Road Closure
I've always wanted to get a good look at a sinkhole. We studied them profusely in a couple of my geography classes when I was a student at Western Kentucky University. Those many aerial shots were certainly cool, but it's not the same as being right there.
What Is a Sinkhole?
Of course, the very nature of a sinkhole COULD make that a risky proposition, although they have yet to deal with further expansion of the one that swallowed up Corvettes in Bowling Green a decade ago. Of course, that's cave country, and that makes south central Kentucky ripe for sinkhole formation. Not to get too deep in the weeds, but the regions where these things develop are identified as karst terrain. Let's get a little help from the U.S. Geological Survey on what that means:
These are regions where the types of rock below the land surface can naturally be dissolved by groundwater circulating through them. Soluble rocks include salt beds and domes, gypsum, limestone and other carbonate rock. When water from rainfall moves down through the soil, these types of rock begin to dissolve. This creates underground spaces and caverns.
Henderson Sinkhole
Well, there you go. We've had a TON of rain over the last month, so it shouldn't come as a surprise that the City of Henderson posted this:
The period of closure isn't prohibitively long, but that sinkhole IS a reminder of what can happen when the sky opens up and stays open for nearly 24 hours. I know Wathen Lane is a great shortcut to the twin bridges from U.S. 60, but until this thing gets cleared up, alternate routes will be required.
