The Henryetta Coal Formation is a geologic formation in Oklahoma. It contains fossils dating back to the Carboniferous period. [1]
As of a 1955 government report, the mapped area of the Henryetta mining district included about 168 square miles in Okmulgee County. Coal occurred in the Senora formation in two minable beds: the Morris bed and the overlying Henryetta bed. The Morris bed averaged about 16 inches in thickness, while the Henryetta coal bed averaged about 25 to 36 inches in thickness. The coal in both beds was of high volatile A and B bituminous ranks. Remaining coal reserves were estimated to be 275 million tons, 271 million tons of which was in the Henryetta bed. [2]
Okmulgee County is a county in the U.S. state of Oklahoma. As of the 2020 census, the population was 36,706. The county seat is Okmulgee. Located within the Muscogee Nation Reservation, the county was created at statehood in 1907. The name Okmulgee is derived from the Hitchita word okimulgi, meaning "boiling waters".
Dewar is a town in Okmulgee County, Oklahoma, United States. The population was 763 at the 2020 census. Founded in 1909 by workers for the Missouri, Oklahoma and Gulf Railway (MO&G), it was named for William Peter Dewar, a railroad official. It incorporated in 1909.
Henryetta is a city in Okmulgee County, Oklahoma, United States. The population was 5,640 at the 2020 census.
Okmulgee is a city in, and the county seat of, Okmulgee County, Oklahoma and is part of the Tulsa Metropolitan Area. The name is from the Mvskoke word okimulgee, which means "boiling waters". The site was chosen because of the nearby rivers and springs. Okmulgee is 38 miles south of Tulsa and 13 miles north of Henryetta via US-75.
Schulter is a town in Okmulgee County, Oklahoma, United States. The population was 422 at the time of the 2020 census.
The Laramie Formation is a geologic formation of the Late Cretaceous (Maastrichtian) age, named by Clarence King in 1876 for exposures in northeastern Colorado, in the United States. It was deposited on a coastal plain and in coastal swamps that flanked the Western Interior Seaway. It contains coal, clay and uranium deposits, as well as plant and animal fossils, including dinosaur remains.
The Casselman Formation mapped sedimentary bedrock unit in Pennsylvania, Maryland, and West Virginia, of Pennsylvanian age. It is the uppermost of two formations in the Conemaugh Group, the lower being the Glenshaw Formation. The boundary between these two units is the top of the marine Ames Limestone. The Conemaugh Group overlies the Upper Freeport coal bed of the Allegheny Formation and underlies the Pittsburgh coal seam of the Monongahela Group.

The Conemaugh Group overlies the Upper Freeport coal bed of the Allegheny Formation and underlies the Pittsburgh coal seam of the Monongahela Group.
The Waynesburg Formation is a coal, sandstone, and siltstone geologic formation in West Virginia and Pennsylvania. It preserves fossils dating back to the Permian period.
The Alum Bluff Group is a geologic group in the states of Georgia, Florida, and Alabama. It preserves fossils dating back to the Neogene period.
The Annona Chalk is a geologic formation in Arkansas, Texas, Louisiana, and Oklahoma. It preserves fossils dating back to the Cretaceous period. The formation is a hard, thick-bedded to massive, slightly fossiliferous chalk. It weathers white, but is blue-gray when freshly exposed. The unit is commercially mined for cement. Fossils in the Annona Chalk include coelenterates, echinoderms, annelids, bivalves, gastropods, cephalopods, and some vertebrate traces. The beds range in thickness, up to over 100 feet in depth in some areas ., but thins to the east and is only a few feet thick north of Columbus, Arkansas and is completely missing to the east. The break between the Annona Formation and the Ozan Formation appears to be sharp with a few tubular borings up to a foot long extending down from the Annona in to the Ozan.
The Tongue River Member is the uppermost geologic member of the Fort Union Formation in Montana, North Dakota, Wyoming. The strata are yellow or light-colored massive sandstones and numerous thick coal beds.
The Hartshorne Formation is a geologic formation in Arkansas and Oklahoma. It preserves fossils dating back to the Carboniferous period.
The Oologah Formation is a geologic formation in Oklahoma. It preserves fossils dating back to the Carboniferous period.
The Welden Limestone is a geologic formation in Oklahoma. It preserves fossils dating back to the Carboniferous period. It is restricted to the Lawrence Uplift of southern Oklahoma. In this region, the Welden Limestone is the only carbonate unit deposited during the span of time from Late Devonian to the Pennsylvanian.
The Lebo Member is a geologic member of the Fort Union Formation in Montana and Wyoming. It preserves fossils dating back to the Paleogene period.
The Kern River Beds Formation is a Neogene Period geologic formation in the southeastern San Joaquin Valley, within Kern County, California.
Coalton is a populated place in Okmulgee County, Oklahoma. It is less than 11 miles south of the City of Okmulgee, and just east of US Route 62/US Route 75. In the Henryetta Coal Formation coal-mining region and an oil-producing area, the town in its heyday had its own newspaper, The Coalton Enterprise, and was along the route of the shortline Coalton Railway, later called the Okmulgee Northern Railway, which operated from Okmulgee south along the Deep Fork River carrying the coal out of the Coalton, Schulter and Dewar producing areas from 1916 to 1964. The Thirty-sixth annual report of the Department of Mines and Minerals from 1943 shows production by two coal companies in Coalton—Coalton Coal Company and Davis Coal Company—of almost 17,000 tons annually.
Kusa is a populated place located in Okmulgee County, Oklahoma, about 4 miles east-northeast of Henryetta. Officially incorporated March 27th, 1916, and located in the Henryetta Coal Mining District, Kusa became a coal mining and lead smelting boomtown, complete with movie theaters, hotels, and banks. It even had its own newspaper, The Kusa Industrial, which published between 1914 and 1920. The population grew to a size of about 3,500, making it the largest town in the county at one point.
The Okmulgee Northern Railway Company (ON), originally the Coalton Railway, was a shortline rail carrier in Okmulgee County, Oklahoma. It was in operation from 1916 to 1964.
