Post office
The Black Butte Mine, developed by S. P. Garoutte in the 1890s, led to the establishment of a post office at Black Butte. William Harris was the first postmaster, and the office, established in 1898, was known by his last name, Harris. The name was changed in 1901 to Blackbutte. It operated under that name until permanently closing in 1957.
Pollution
In the 21st century, the former mine and the area around it have become a Superfund site. The Environmental Protection Agency is concerned about methylmercury contamination of streams including Garoutte Creek, the Little river" target="_blank">River, and the Coast Fork, as well as the Cottage Grove Reservoir on the Coast Fork. During its heyday, the mine was the second-largest mercury producer in Oregon. From 1900 to 1957, it yielded a total of 16,904 flasks of elemental mercury; equivalent to about 13 million pounds (5,900,000 kg).
