Alexander Springs, Ocala National Forest, FL; June 2009
This photo was taken at Alexander Springs, in the Ocala National Forest, in central Florida. The water in the photograph is Alexander Creek.
From the Alexander Springs website description:
The spring is set in a low area with thick sub-tropical forest on two sides and pines and hardwoods in a camping area on the other. The spring pool is a large semi-circle about 200 feet across and forming the headwaters of Alexander Creek. Water flows from a cavernous opening near the middle of the pool. The depth of the pool gradually increases to about 6 feet over the course of 60 feet. The bottom in this shallow portion is sandy. There is then a 40-foot-wide fringe of aquatic vegetation before the bottom falls away suddenly to reveal a large open area of exposed and sand-covered limestone rock and boulders. The area forms a sunlit trench that is 45 feet long, 10-25 feet wide, and about 28 feet deep. Water flows strongly from a large opening on the bottom on the beach side of the spring. Water in the spring is very clear and can be bright blue over the vent area. Flow from the spring creates a large and powerful surface boil that is readily visible from the shore.
Fish, including bluegill, may be observed swimming among the aquatic plants and over the trench. The spring run narrows outside the pool and winds first SE then NE a total of about 25 miles to the St. Johns River in the Lake Woodruff National Wildlife Refuge. There is abundant wildlife in the run, including alligators.
