Reference
=Linton Diamond Coal Mine= The Linton Diamond Coal Mine was a coal mine Saline Township, Jefferson County Ohio, active from 1855-1921. It was a drift mine with a seam up to 2.7 m. It is a Middle Pennsylvanian Konservat-Lagerstätte, with at least 35 genera known from over 7,000 specimens found in a layer of fosiliferous cannel under a layer of upper freeport bituminous coal.

History
In April of 1774, the mouth of Yellow Creek, a nearby tributary of the Ohio river, was the sight of the Yellow Creek Massacre, in which the family of Mingo chief Logan was lured from their campsite across the Ohio river where they were murdered by Jacob Greathouse and his party. This event was influential in the start of Dunmore's War later that year.

The first records of the Linton community date to 1803 in the form of a post office originally known as "Mouth of Yellow Creek", but in 1855 it was renamed to "Linton Post Office". Period maps also detail about 2 dozen dwellings, the Linton Hotel, and the Yellow Creek railway station. Small mines existed prior to 1855, however, due to a lack of nearby railroads, these small scale operations existed mainly to serve local needs. The completion of the Cleveland and Pittsburgh Railroad in 1852 prompted commercial coal mining in the area. In 1855, buisnessmen from New Haven, Connecticut, purchased a section of land and opened a drift mine under the name of the Ohio Diamond Coal Company. The mine extracted bituminous coal, which was part of the Upper Freeport coal of the Allegheny group and reached a thickness of up to 2.7 m and existed approximately 12 m under the surface, but is exposed in some areas due to erosion. This original mine defauted within two years and was sold to Samuel Nessly at a sheriff's sale. Nessly continued operations under the original name until the mine was closed in 1892.

The cannel floor of the mine made for a sturdier surface than the softer rocker underneath, so the use of pillars was reduced and the rooms were up to 6.5 m wide. The mine had a good safely record, but suffered from poor ventilation. Mine activity peaked in the 1870s, with an average of 20 workers and between 250 MT and 272 MT of coal extracted per day which was used entirely by the railroad. By 1892, the mine had closed after several years of decreased activity.

The mine was reopened in 1917 by the River Ridge Coal Company of Cleveland, Ohio, with the purpose of removing the remaining pillars. This was completed by 1921, when the mine was closed for its final time. Surface operators carried out small operations nearby until roughly the late 1960s, removing small veins near the original seam. These operations were often named after the original Diamond mine, because of its renown in the area. With the end of the original Diamond Mine came the end of the nearby village. The Linton Post Office closed in 1901, causing the name of Linton to fall into obscurity. The local Linton Hotel was later known as the Waterford Downs, which had good commercial success until it burnt down in the 1970s.
