scubafool:I have heard about Blue Sink in Ocala National Forest, but I have never been able to find out anything about it. Many thanks, as this is less than an hour's drive from me.
Question, though. I pulled up NFS 573 and SR 19 on MapQuest, and got an aerial shot of the area. Is Blue Sink the dark spot to the west of SR 19, north of 573 just after 573 makes a curve to the left?
I looked it up on google earth and it looks like it is 1.35 miles WNW of the small lake you're talking about. There is a large open sandy space about 100 yards NW of it that can be seen on G-earth.
