Devil's Millhopper Geological State Park
|Devil's Millhopper Geological State Park|
IUCN category V (protected landscape/seascape)
|Location||Alachua County, Florida, USA|
|Nearest city||Gainesville, Florida|
|Area||67 acres (270,000 m2)|
|Governing body||Florida Department of Environmental Protection|
The park is maintained by the Florida State Parks system, a division of the Florida Department of Environmental Protection. The park is adjacent to San Felasco County Park, and near the San Felasco Hammock Preserve State Park.
The cutaway, limestone sides of the sinkhole provide an easily visible geological record of the area. Twelve springs, some more visible than others, feed the pond at the bottom of the sinkhole. In the summer, the bottom of the sinkhole is dramatically cooler than the air at the surface due to the depth and shade from the canopy above. Significant fossil deposits include shark teeth, marine shells, and the fossilized remains of extinct land animals.
Even though the park is only 71 acres (290,000 m2), three distinct ecological environments exist in the park, based on exposure to sun, fire, and water. In the sandhill environment, the sandy soil and regular fires result in pine trees being the predominant vegetation. The moist soils of the hammocks support broadleaf trees and more low vegetation, while the swamp areas only support flora and fauna adapted to year-around wet conditions.
The 120 foot (40 m) deep, 500 foot (150 m) wide sinkhole got its name from its similar appearance to the hopper of a mill, along with the bones found at the bottom, suggesting animals entered it on the way to meeting the devil. The Millhopper was owned for a time by the science department at the University of Florida and used as a research site for the students. Its unique ecosystem made it an invaluable resource for study. However, the Millhopper was often used by students as a place to socialize and have parties, which led to problems with litter and erosion from foot traffic. The site was purchased by the state in 1974, and a set of 236 wooden steps, along with boardwalks and an observation deck at the bottom were completed in 1976 to allow access to the sink for visitors without further soil erosion.
