The Hell Creek Formation, Montana: a Stratigraphic Review and Revision Based on a Sequence Stratigraphic Approach
Review The Hell Creek Formation, Montana: A Stratigraphic Review and Revision Based on a Sequence Stratigraphic Approach Denver Fowler 1,2 1 Badlands Dinosaur Museum, Dickinson Museum Center, Dickinson, ND 58601, USA; [email protected] 2 Museum of the Rockies, Montana State University, Bozeman, MT 59717, USA Received: 12 September 2020; Accepted: 30 October 2020; Published: date Supporting Information 1. Methods: Lithofacies Descriptions Facies descriptions follow methodology laid out in Miall (1985). Descriptions mostly follow those of Flight (2004) for the Bearpaw Shale and Fox Hills Sandstone. Additional lithofacies are described for the Colgate sandstone, ?Battle Formation, an undivided Hell Creek Formation, and the lowermost 5–10 m of the Fort Union Formation. It was desirable to stay as close to Flight's (2004) definitions as possible in order to facilitate cross comparison between measured sections and interpretation; however I have also chosen to remain true to the intentions of Brown (1906) in keeping the Basal Sandstone (and associated basal scour) as the first unit of the Hell Creek Formation, rather than the tidal flats identified by Flight (2004). This analysis is not as concerned with the nature of the basal contacts as much as internal stratigraphy within the Hell Creek Formation itself, hence some of the stratal and facies relationships described by Flight (2004) were not directly observed by myself, but I have included them here to ease comparisons. 1.1. Bearpaw Shale The Bearpaw Shale is the basalmost formation considered in this study; as such only the uppermost 10–20 m have been observed in outcrop. In this upper 20 m or so, the Bearpaw Shale generally coarsens upwards, predominantly comprising shale with occasional interbedded sandstone. -

Lynn Kinter Laramie, Wyoming, was established as a railroad con- trains also used 2 million gallons of water each day from the struction town in May, 1868. The transcontinental railroad Laramie River. Stops along the track where coal and water (Union Pacific) came across the Rockies in the late 1860s, were available developed into towns, for example, Rawlins across the then unsettled landscape that now contains and Rock Springs. We left town heading southwest via Cheyenne and Laramie, after a southern route through Highway 230. Elevation at Laramie is 7,170 ft (2,185 m), and Colorado was rejected because of the terrain. A relic of the precipitation is 10.5 inches (26 cm), most of which falls in Tertiary Ogallala formation called the “Gangplank” west of March through July. Cheyenne provided an access ramp across the mountains; Stop 1: University of Wyoming, Monolith Ranch by this was the first place north of Denver where it was feasible the fishing access to a Laramie River site with greasewood to build the railroad. It was also the first place west of (Sarcobatus vermiculatus). This is an area that was farmed Missouri that railroad ties could be cut from the surrounding at the turn of the last century. In 1906, a grain elevator forests, and railroaders timbered for ties extensively in the capable of loading 50,000 bushels onto railroad cars daily Laramie and Snowy Ranges (about 3,000,000 ties were cut was built in Laramie. -
