Before a sinkhole formed, the landform most likely present was a karst landscape. This type of terrain is characterized by soluble rock, such as limestone, which can be eroded by water over time, creating underground voids. When these voids become too large to support the overlying material, the ground collapses, leading to the formation of a sinkhole. Other features like valleys or depressions may also be common in such landscapes.
