Abstract

A 107-m (350 ft) section of coal-bearing rocks of the Upper Cretaceous Mesaverde Group that is exposed along an access road to the Edna Mine in Routt County, Colorado, records deposition of sediment during a regressive phase of the epicontinental sea. Each of the coal beds in the section occurs at the top of a bayfill sequence that records infilling of a bay sufficient to provide swamp conditions and allow formation of peat.
