 Warm Mineral Springs

12200 San Servando Ave., North Port, FL 34287
(Owned and Operated by the city of North Port)

 From the Sarasota County History Center

The surface area of the spring is a round pond, it is 1.4-acre in circumference and reaches depths of nearly 250 feet deep in the center.
The hourglass shaped sinkhole (or cenote) is the results of an apparent earthquake that created the subsurface cave-in some 20,000 years ago. At about 45 feet below the surface there are small ledges that encircle the basin, some of which contain shallow caves. Beneath these ledges the springs body expands to form a large cavity where, at about 148 feet below surface, debris accumulates and forms a "Debris Cone" that is thought to be over 30,000 years old.

The limestone bedrock, from which the sinkhole is formed, comes from marine rock. United States Geological Society hydrologists found the porosity of the limestone formation allowed water interchange with the ground water. Water samples collected from the Floridian Aquifer have revealed that the underground water may have taken 60,000 years to filter through the earth before reaching the surface. The discovery of stalactites and stalagmites found in the caves below the spring’s surface indicates that the underwater caves were dry, probably during the last Ice Age.
