Pittsburg-Weir Coalfield
The Pittsburg-Weir Coalfield, also known as Weir-Pittsburg Coalfield and Cherokee Coalfield, is a coalfield located in Cherokee and Crawford counties in the southeast corner of Kansas.
The first underground shaft mine was built in the region in 1874 near Scammon. Prior to that, there was scattered small-scale drift mining and surface mining of coal, but the construction of the first shaft mine ushered in an era which eventually led to as many as 290 significant mines and numerous other small ("dinky") mines in the two counties. The most active period of mining in the region was 1890-1910, and most of the coal camps were dismantled by the 1930s or 1940s. Mechanized strip mining overtook underground mining in output in 1931, and that combined with competition from eastern coal led to a demise in importance of underground mining in the region.〔http://www.kancoll.org/khq/1972/72_2_powell.htm〕
