Above the river on the west side at Pulltite Spring and above the bluff line is the Sunkland with approximately 80,000 acres of large sink holes. The description of the 6000 acre Natural Area within the Sunkland has the following description “Over 6,000 acres of hills and hollows draining into Boyds Creek and the Current River. At the center of this natural area is a complex of sinkholes, depressions caused by the dissolving of the underlying rock, in this case dolomite, followed by a collapse of the land’s surface. What is known as the “sunkland” is the longest conspicuous sinkhole in Missouri, nearly a mile long, 200 feet deep and 600 feet wide. It is so large that to the casual observer it looks like a normal valley” (Missouri Dept. of Conservation-Sunkland, 2020). I Can’t wait to go there and explore.
