Elk Basin
Elk Basin is a valley on the border of Montana and Wyoming in the United States. It is an active oil field with hundreds of derricks operating in it. Geologically, it is a breached anticline formed by a deep subsurface thrust fault. Most of the rocks at the surface are Cretaceous in age, including the Lance Formation, Meeteetse Formation, Mesaverde Formation, Cody Shale, and Frontier Formation. Teaching Geology As the rock strata in the basin are mostly exposed and relatively easy to identify, Elk Basin has long been used as a place for geology students to learn to practice geologic mapping. Often mapping classes are supported by the Yellowstone Bighorn Research Association, located in Red Lodge, Montana Red Lodge is a city and county seat of Carbon County, Montana, United States.

Elk Basin MT WY
The elk (''Cervus canadensis''), also known as the wapiti, is one of the largest species within the deer family, Cervidae, and one of the largest terrestrial mammals in its native range of North America and Central and East Asia. The common name of "elk" is open to confusion, as "elk" is the name used in British English for the larger ''Alces alces'', with similar names used by other European languages (German ''Elch'', Swedish ''älg'', and French ''élan''). In North America, the common name for ''Alces alces'' is "moose". The name "wapiti" is sometimes used for ''Cervus canadensis'', which derives from the Shawnee and Cree word ''waapiti'', meaning 'white rump'. Elk range in forest and forest-edge habitat, feeding on grasses, plants, leaves, and bark. Male elk have large antlers which they shed each year. Males also engage in ritualized mating behaviors during the rut, including posturing, antler wrestling (sparring), and ''bugling'', a loud series of vocalizations ...

Red Lodge, Montana
Red Lodge is a city and county seat of Carbon County, Montana, United States. As of the 2020 census, the population of the city was 2,257. History On September 17, 1851, the United States government signed a treaty with the Crow Nation, ceding the area which now contains Red Lodge, MT to the Crow Indians. Rich coal deposits were found there in 1866, and gold was discovered nearby in 1870. An 1880 treaty between the U.S. government and the Crow allowed the area to be settled starting April 11, 1882. The Red Lodge post office was established on Dec 9, 1884 with Postmaster Ezra L. Benton. A rail line was constructed into town, and coal shipments began in June 1889. The boundaries of the Crow Reservation were redrawn October 15, 1892, opening the whole area to settlement. From then until the 1930s, coal mining defined the town. In the late 19th century, many new settlers came to Red Lodge, MT. The majority came from Italy, the British Isles, Finland, Norway, Sweden, Germany, a ...

Geologic Map
A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults, folds, are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features. Stratigraphic contour lines may be used to illustrate the surface of a selected stratum illustrating the subsurface topographic trends of the strata. Isopach maps detail the variations in thickness of stratigraphic units. It is not always possible to properly show this when the strata are extremely fractured, mixed, in some discontinuities, or where they are otherwise disturbed. Symbols Lithologies Rock units are typically represented by colors. Instead of (or in addition to) colors, certain symbols can be used. Different geologic mapping agencies and authorities have different standards for the colors and symbols to be used for rocks of dif ...

Stratum
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and '' lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Frontier Formation
The Frontier Formation is a sedimentary geological formation whose strata date back to the Late Cretaceous. The formation's extents are: northwest Colorado, southeast Idaho, southern Montana, northern Utah, and western Wyoming. It occurs in many sedimentary basins and uplifted areas. The formation is described by W.G. Pierce as thick, lenticular, grey sandstone, gray shale, carbonaceous shale, and bentonite. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, North America)."

Mesaverde Formation
The Mesaverde Group is a Late Cretaceous stratigraphic group found in areas of Colorado, New Mexico, Utah, and Wyoming, in the Western United States. History The Mesaverde Formation was first described by W.H.Holmes in 1877 during the Hayden Survey. Holmes described the formation in the northern San Juan Basin as consisting of three units, which were a "Lower Escarpment" consisting of 40 m of ledge- and cliff-forming massive sandstone; a "Middle Coal Group" consisting of up to 300 m of thick slope-forming sandstone, shale, marl, and lignite; and an "Upper Escarpment" consisting of 60 m of ledge- and cliff-forming sandstone. A.J. Collier redesignated these units in 1919 as the Point Lookout Sandstone, the Menefee Formation, and the Cliff House Sandstone, and raised the Mesaverde Formation to group rank. The group was later traced to the greater Green River Basin, the Uintah and Piceance Basins, the Bighorn Basin, the Front Range, the Zuni Basin, the Wasatch Plateau, Wind ...
