Fontanet, two miles west of
Coal Bluff, was also an important mining town worked and operated by the Coal Bluff Mining Company. The town also was an important
railroad station on the Indianapolis and St. Louis Railroad. The mining company had a large general store, and in 1890 over 300 miners lived in Fontanet. The town's post office was established under the name Fountain Station in 1870. It was renamed to Hunter in 1877, and again to Fontanet in 1881. The post office is still in operation as of April 2017. On 15 October 1907, approximately 40,000
kegs of powder exploded at the
DuPont Powder Mill of Fontanet, Indiana, killing between 50 and 80 people, and destroying the town. The sound of the explosion was heard over 200 miles (320 km) away, with damage occurring to buildings 25 miles (40 km) away. ==Education==
