The largest of the karst sinkholes of Ladeyny Log, which is visible even on satellite images, is the Smirnov Sinkhole, also called the Ladeyny Sinkhole or the Karst Sinkhole. A long time ago, part of the area fell into a huge underground cavity and a "sinkhole" the size of a football field appeared.
