Bone Valley

These roads are no longer traveled by man.

Millions of years ago, the coast of Florida was believed to be 60 miles further inland. In the 1890s, Smithsonian archaeologists discovered large amounts of fossils in prehistoric sea beds across central Florida. After the fossil discovery, the region 40 miles South of Orlando became known as Bone Valley.

The prehistoric sea floor was located 25 feet below the surface. It was encompassed in a phosphate matrix comprised of animal bone, sand, and clay. Scientists knew that the phosphate surrounding the fossils made a great fertilizer. However, it wasn’t until the 1960s that phosphate fertilizers became chemically enhanced, increasing crop yields tremendously.

Throughout the turn of the century, the Bone Valley region boomed as a dozen commercial mining companies moved to the region from the North. Early miners worked by hand using only a pickaxe and wheel barrow. It would take miners several years to mine 15 acres. By 1910, mechanized steam shovels were capable of doing the work of 80 men.

By the 1920s, Florida 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 the 1920s. At its peak, the town of Nichols had a population of 400.

IMG_5942.JPGWorkers rented housing from their employers with water, electricity, and garbage collection included for a small fee. This was available to them only until they retired. Some 2-story homes were rented to multiple families. These communities included their own general store, hospital, and school. Although the Post Office still remains open today, the town was phased out completely in the 1950s after families started moving to nearby cities for better opportunities.

 Mobil Mining and Mineral Company, a subsidiary of Mobil Oil, purchased 3 mines across Bone Valley, 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 moved to nearby communities.

The demand for phosphate peaked in the early 1980s. There were over 14,000 employees mining and processing phosphate across Bone Valley by 1985. By the late 1980s, foreign countries began investing heavily in mining production and their own processing plants.  This sharply decreased their need to import phosphate from the United States.

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

This processing plant was once one of the largest in Bone Valley consisting of over 10,000 acres. The facility closed down permanently in 2004, after 60 years of service.

A custom built switchboard made for Mobil was stripped of all its wiring.

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