Marker text: SITE OF THE DISCOVERY OF PHOSPHATE IN FLORIDA
One block to the south is the site of the discovery of hard rock phosphate in Florida by Albertus Vogt in 1889. It made Dunnellon a boom town and first center of the industry. The Tiger Rag, Early Bird and Eagle mines were among the most valuable. The Marion County Phosphate Co. was the first to operate extensively. Phosphates are still mined in the area, but since 1900 the center of production has shifted elsewhere.
