We are looking at buying land in Dekalb county. There are 3 sinkholes a few feet deep and maybe 7-10 feet wide. It is on a small “mountain”, a few streams flow down this hill as well as there is a cave at the bottom where the water is gathered from in a cistern. Are these dangerous? Is it bad to buy land with sinkhole activity like this? I’m worried, but everyone tells me they are normal in TN.
It's pretty normal in Tennessee which has more caves than any other state in the U.S. In many locations in Middle Tennessee, there is no way to escape karst because it is all underlain by limestone. One thing you can do is go back and look at older aerial photographs to see if the sinkholes were there in their current configuration. If so, they are probably pretty stable. If there is a lot of soil and vegetation growth in the sinkhole itself, that may be further proof of its stability.
