Copperas Mine Fork is a tributary of Island Creek, 9.3miles long,[3] in southern West Virginia in the United States. Via Island Creek and the Guyandotte and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of 45.4sqmi[4] in a rural area on the unglaciated portion of the Allegheny Plateau, in the Logan Coalfield. The Copperas Mine Fork's entire course and drainage area are in Logan County.[5]
The Copperas Mine Fork rises in western Logan County, along its boundary with Mingo County, and flows generally eastward through the unincorporated communities of Sulphur Springs, Beebe, Holden, and Cora, to Mount Gay, where it flows into Island Creek from the west, approximately 1miles west of the city of Logan.[5]
