The Devil’s Millhopper is a 117-foot sinkhole that formed when the roof of an underground cave collapsed. It is now a National Natural Landmark and it’s evil sounding name comes from its funnel like shape (early farmers fed grain into a hopper) and because fossilized bones and teeth were found a the bottom legend was that the millhopper fed bodies to the devil, hence the name. Also circulating is the The legend of the Devil’s Millhopper in which the Devil wants to marry and Indian Princess who wanted nothing to do with him, the Indian braves attempted to rescue her and the Devil turned 
the ground into a giant sinkhole. As the Indians were trying to climb out he turned them to stone and the weeping of water from the stones is said to be the Indian braves crying for their Princess.
We enjoyed our walk down and reading the interpretive signs along the way. It was beautiful and we were the only ones there! With some mist and a bit of fog it was like a scene out of a film. It also smelled wonderful—very fresh and green.
The outdoor visitors center (brrr cold) that has some artifacts that were found 
there. It isn’t very large, but the boys enjoyed looking at the fossils and bones.
Our focus on this trip was to see what an actual sinkhole looks like and to discuss how they are formed. I think we accomplished our goal and had a good time doing it.
The Devil’s Millhopper is the only geological site in the Florida State Park system.
WOW! Very interesting!
