The abandoned Bone Valley phosphate plant

Bone Valley encompasses portions of present-day Hardee, Hillsborough, Manatee, and Polk counties. This area contains several phosphate processing plants that assist in the production of agricultural fertilizer. Florida contains the most massive known deposits of phosphate in the United States. Millions of years ago, the Florida coast was believed to be sixty miles further inland. In the late 19th century, Smithsonian archaeologists discovered significant amounts of fossils in prehistoric sea beds across Central Florida. After the fossil discovery, the region forty miles south of Orlando became known as Bone Valley.

The old sea floor was located twenty-five feet below the surface. The phosphate matrix is made up of animal bone, sand, and clay. Scientists knew that the phosphate surrounding the fossils made an excellent fertilizer. It was not until the 1960s that phosphate fertilizers became chemically-enhanced, which increased crop yields tremendously.

Throughout the turn of the 20th century, the Bone Valley region boomed as a dozen commercial mining companies moved to Central Florida from the North. Early miners worked by hand, using only a pickaxe and wheelbarrow. It would take miners several years to mine only fifteen acres. By 1910, mechanized steam shovels were capable of doing the work of eighty men.

By the 1920s, Bone Valley became the main source of phosphate for American farmers. Approximately 75 percent of the phosphate used by farmers and gardeners across America was mined in Bone Valley. Phosphate was also sold and shipped overseas.

The town of Nichols was built in 1905 by Virginia-Carolina Chemical Company. They named it after nearby Fort Nichols, which was used in the Seminole War. The community consisted of about 120 houses with some dating back as early as 1920. At its peak, the town of Nichols had a population of 400.

Workers rented housing from their employers with water, electricity, and garbage collection included for a small fee. This accommodation was available to them only until they retired. Some families even shared homes. It was not uncommon for multiple families to share a two-story house. These communities included their general store, hospital, and school. Although the Post Office remains open today, the town was phased out entirely in the 1950s after many families moved to nearby cities for better opportunities.

 Mobil Mining and Mineral Company, a subsidiary of Mobil Oil, purchased three mines across the Bone Valley region, including the Nichols mine. It is believed that Mobil built this phosphate processing facility shortly thereafter. In 1960, the remaining company-owned housing was sold to employees and relocated to nearby communities.

The demand for phosphate peaked in the 1980s. Over 14,000 employees were mining and processing phosphate across Bone Valley by 1985. By the late 1980s, foreign countries were investing heavily in mining production and their processing plants.  The overseas plants sharply decreased their need to import phosphate from the United States, causing the processing plants in Bone Valley to become obsolete. By 1988, nearly every phosphate company across Bone Valley was experiencing layoffs and temporary closings. Many of the phosphate plants struggled through the 1990s and ultimately closed as the price of fertilizer decreased rapidly.

Mobil decided the company was getting out of the mining business due to overseas competition and sold the facility in 1996.

After closing, the property was purchased by a private owner at auction. According to the owner, since he bought the facility, the grounds have been a target for vandals and thieves. As much as $3 million worth of scrap metal was stolen from the abandoned plant. There are no plans for the facility at this time. The property remains private, and anyone caught on site will be considered trespassing.

  2. This is really amazing, and your beautiful photos and great background notes have given me some wonderful inspiration for the setting of the UAV (drone) race in the next chapter of my WIP, which I’m writing along with the Discovery Challenge (and is how I found you today). I will certainly pingback once the chapter is written, and I’ll encourage my followers to come here for the photos — thank you so much, I can’t wait to see more of your blog!
