Mining in the Daum Quadrangle
The 1873 atlas of the area showed a coal mine. How long this mine operated or whether other mining took place between the early 1870s and the beginning of recorded production with the 1882 Coal Report is not known. Field work in 1927 discovered another mine in 27-T10N-R11W. It is not known who operated the shaft or when the mining took place. Both mines were likely local mines, operated for a few seasons, with small aerial extent.
