As the sun shines, rainbows play across the bottom of the crystal-clear spring basin at Silver Glen Springs, a beautiful spot along the edge of the Big Scrub of the Ocala National Forest, with a spring run that pours out into Lake George, the largest of the St. Johns River Chain of Lakes, north of Astor. Both a popular day use recreation area and an important archaeological site, Silver Glen Springs showcases the delicate balance necessary between enjoyment of the outdoors and preservation of irreplaceable resources.
