So what causes these sinkholes to form?
University at Buffalo Geology Professor Dr. Marcus Bursik says there are two types of sinkholes. One type is caused by aging infrastructure, like old pipes that burst underground and eventually cause a collapse on the surface. This is more common and is sometimes called a “fake sinkhole.”
Like the Sinkhole on US 82 near Tifton August 2012, caused by a broken water main, and since filled in. The other type is much more common:
The limestone is easily dissolved in water, which creates a hole underground. The surface eventually will not have the support it needs, causing a cave in.
Like the ones in Suwannee County, Florida and points south, including the one that pulled a man from his bed into the ground in Sefner, FL. Also in Albany, GA, and the one that caused Lowndes County to reroute Snake Nation Road. All of these are in the same Floridan Aquifer.
How do you know if you’ve got a sinkhole?
Like the one under Michael McCormick’s garage in Lowndes County?
