Description
Mill Creek (Alachua) Sink is located in the city of Alachua, Florida and was originally established by the NSS as the Alachua Sink Preserve on November 7, 1992. The donor of the property was the Asgrow Florida Corporation, a division of the Upjohn Company. John Kibler, a long time NSS/CDS member and Asgrow employee, was one of the driving forces behind the donation to the NSS. The NSS interest in the ownership of this property is primarily due to its significant value as a hydrological resource and to protect access to this site.

Alachua Sink is a water filled sinkhole connected to a water filled cave and is the only known window to the underground Mill Creek Stream System. The sinkhole slopes steeply nearly 50 feet down to the water's edge. The sinkhole is filled with very dark, tannic-stained water for most of the year, as well as fallen trees and debris. Clear water is not encountered for a considerable distance into the system. The main cave system has tunnel both upstream and downstream with depths to 227 feet.
