In his Annual Report of the Territorial Geologist to the Governor of Wyoming 1890, Louis D.

Since large-scale commercial coal production began in Campbell County in the mid-1970s, most coal companies have changed names, owners, and boundaries several times. To let those changes go unrecorded would be to lose the very beginning of coal in Campbell County.
