Coal Mining in Webster County, Iowa |
 | | Coal is an accumulation of plant material in the form of peat, which has been subjected to pressure and heat. |
 | | In that field a unique seam, the "big coal" sometimes reaching a thickness of ten feet, is in long strips, 200 to 300 feet wide, which curves through the area, possibly a result of the marsh developing in the bed of an old river. |
 | | Webster County historically has had five coal producing areas; the Coalville-Kalo- Holliday Creek district, the Lehigh district, the Skillet Creek district east of Dayton, all of which are on or near the Des Moines River, and the Tara district on Lizard Creek several miles west of Fort Dodge. |
