The mother of all sinkholes, Devil's Millhopper has drawn tourists since the 1880's. More than 120 feet deep and 500 feet wide, this Gainesville sinkhole has formed over tens of thousands of years. Fossilized sharks teeth and other marine life have been found in its bowels, teaching scientists a lot about the natural history of this area.
