It all started when Albertus Vogt found fossilized teeth on his property. The discovery led to what would become a thriving industry . . . hard rock  phosphate mining which began in 1889 with the Marion Phosphate Company near Dunnellon.

Phosphate was found to be useful in agriculture to add nutrients to depleted soils.

The Dunnellon Phosphate Company, owned by Vogt, followed soon after in 1890. The ensuing years saw rapid expansion of the industry to the north and south of Dunnellon. The news created a land rush complete with speculators, gamblers, saloons, conflicting claims

The towns of Inverness, Floral City and Brooksville also shared in the boom which was short lived and played out by the beginning of World War I.

The vast deposits of phosphate that cover large areas of Florida are from the bones and remains of sea creatures that lived in this part of the earth during the late Miocene or Pliocene ages 10 to 15 million years past.

Some of the mines are now recreational areas and campgrounds while others are just ghost names with hard to find evidence recaptured by nature or development. Hard rock mining along the rock phosphate ridge is now a memory accessible by historical museums in each of the towns of the phosphate ridge.

Still today, 80% of all phosphate used in the U.S. and 25% used in the world’s supply is mined from deposits found in other locations in Florida

The towns have since become vibrant communities adjacent to the natural beauty of the Withlacoochee State Forest, Withlacoochee River and Withlacoochee State Trail. The State Trail runs 46 miles from Dunnellon through Inverness and Floral City to Dade City in Pasco County, and connects with Brooksville via the Good Friends trail. The Trail is enjoyed by cyclists, hikers and horseback riders. Water sport enthusiasts will find the Withlacoochee river a quiet wilderness teeming with wildlife as it meanders north to Dunnellon and Lake Rousseau and on to the Gulf of Mexico.history description

The Trail


biker on trail

Dunnellon was founded in 1887. In 1889, phosphate was discovered in the area, leading to an expansion of the area until the early 1910s. The original mining took place in and around the Rainbow River, using the river's natural flow to transport phosphates.


Inverness Shot of Downtown

The city of Inverness was originally named "Tompkinsville". Settlement of the area dates back to 1868. A. D. Tompkins, later known as "Uncle Alf", started the community. To attract newcomers to the town, he established mail service and helped erect the first sawmill in the county. He gave his brother-in-law, Frank M. Dampier, Sr., a lot to build a store, with Dampier becoming the first merchant in town. Dampier is credited with laying out the town and naming it Tompkinsville. Not many years later, the town of Tompkinsville was sold to a firm in Jacksonville, and the name was changed to "Inverness".

Floral City

Floral City History

Floral City was laid out and surveyed in 1883 by the surveyor W.H. Havron and then-Senator Austin S. Mann. The land was owned by James Baker, son-in-law of ex-Confederate soldier John Paul Formy-Duval, an early area settler and landowner. The village was at one time larger than Miami, due to the phosphate mining industry located in Citrus County. Around the time of World War I, the mining industry shut down in Floral City. After the war, mining was moved south to the Bartow area east of Tampa. The community is said to be a slice of "Old Florida" that remains relatively intact. The town was named Floral City for its abundance of wild flowers, which are still plentiful today.


Preston Smith Brooks Member of the US House of Representative

In 1856 the county seat of Hernando County became the newly named town of Brooksville. The name was chosen to honor Preston Brooks. Brooks, a congressman who nearly caned abolitionist Senator Charles Sumner to death in 1856 on the floor of the Senate after Sumner gave an anti-slavery speech and disparaged Brooks' uncle, Senator Andrew Butler. The Pierceville post office was not renamed for Brooksville until 1871. The city was incorporated on October 13, 1880.
