Course Sinkholes: A Far More Common Issue Than You May Understand

Chances are thereas a good chance youave heard the bizarre (and terrifying) history of Mark Mihal, the man who was just playing a of golf in Waterloo, Illinois, looking at the class, minding their own businessa when he fell into an sinkhole that hadnat previously been apparent. Luckily he only suffered minimal injuries, but the possibility of the earthas surface beneath you suddenly changing into a crater that virtually eats you alive like the Sarlacc remains disturbing, to say the smallest amount of. Hereas what the sinkhole seemed like: Mad, right? Wella yes, ridiculous, but not as much as it might look on the face area of it. While here is the first such story we are able to remember reading about, course sinkholes actually arenat all that uncommon. Each time a person was killed in Japan after falling right into a sinkhole on a training course that opened up below her and however, in 2009, an identical history to Mihalas ended in disaster. An image of that sinkhole: Furthermore, last November, a blog about maintenance at the course at By Oaks Country Club in Houston contributed many photographs of two sinkholes on the course, and the repair process: Not quite as remarkable whilst the preceding two, but a sinkholeas a sinkhole. And the movie below displays numerous sinkholes that opened on a Florida course this past year (and also features Mark Joyella, formerly of our sister site Mediaite ): Soa why all of the sinkholes? Effectively, hereas a primer on how theyare formed: Rain percolating, or seeping, through the land absorbs co2 and responds with decaying vegetation, creating a slightly acidic water. That water moves through spaces and breaks undercover, slowly dissolving limestone and making a network of cavities and voids. As the limestone dissolves, pores and cracks are increased and take much more acidic water. Sinkholes are produced when the land surface above breaks or sinks into the cavities or when surface material is moved downward into the voids. So itas not so much that golfing courses themselves are good to sinkhole creation as it is that areas with lots of limestone (or similarly permeable rock) underground are prone. Probably the drainage systems at golf courses create a stream of water that helps this process along (aSinkholes could be brought about by human activities such as: overwithdrawal of groundwater, diverting surface water from the large place and concentrating it within a place, artificially making wetlands of surface water, positioning new water wellsa), but as non-experts in earth science, we canat say such a thing without a doubt on that front. What we could say for sure: this history didn't make us desire to go golfing.
