'Shows the elk herds at Jackson Hole, Wyoming, including views of them calving, duelling, feeding, and dying. Also shows grouse and moose.'
'A Biological Survey Picture.'
Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The elk (Cervus canadensis) or wapiti is one of the largest species within the deer family, Cervidae, and one of the largest terrestrial mammals in North America, as well as Central and Northeast Asia. It is not to be confused with the still larger moose (Alces alces) of North America, alternatively known as "elk" in British English and related names in other European languages (German Elch, Swedish älg, French élan), in reference to populations in Eurasia. Elk range in forest and forest-edge habitat, feeding on grasses, plants, leaves, and bark. Male elk have large antlers which are 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 that establishes dominance over other males and attracts females.
Although it is currently native to North America and eastern Asia, it had a much wider distribution in the past. Populations were present across Eurasia into Western Europe during the Late Pleistocene, and survived into the early Holocene in southern Sweden and the Alps. The elk has adapted well in countries where it has been introduced, including Argentina and New Zealand. Its adaptability may in fact threaten endemic species and the ecosystems into which it has been introduced.
Elk are susceptible to a number of infectious diseases, some of which can be transmitted to livestock. Efforts to eliminate infectious diseases from elk populations, largely by vaccination, have had mixed success. Some cultures revere the elk as having spiritual significance. In parts of Asia, antlers and their velvet are used in traditional medicines. Elk are hunted as a game species. Their meat is leaner and higher in protein than beef or chicken. Elk were long believed to belong to a subspecies of the European red deer (Cervus elaphus), but evidence from many mitochondrial DNA genetic studies beginning in 1998 shows that the two are distinct species. Key morphological differences that distinguish C. canadensis from C. elaphus are the former's wider rump patch and paler-hued antlers...

Jackson Hole (originally called Jackson's Hole by mountain men) is a valley between the Gros Ventre and Teton mountain ranges in the U.S. state of Wyoming, near the border with Idaho. The term "hole" was used by early trappers, or mountain men, as a term for a large mountain valley. These low-lying valleys, surrounded by mountains and containing rivers and streams, are good habitat for beavers and other fur-bearing animals. Jackson Hole is 55 miles long (89 km) long by 6-to-13 miles wide (10 to 21 km) and is a graben valley with an average elevation of 6,800 ft (2,100 m), its lowest point being near the southern park boundary at 6,350 ft (1,940 m)...
The valley is formed by the Teton Range to the west and the Gros Ventre Range to the east. Grand Teton National Park occupies the northwestern part of the valley, encompassing much of the Teton Range and Jackson Lake. The city of Jackson is at the southern end. Between them lies, on U.S. Route 26, "Glacier View Turnout" offering a view of Teton Glacier on the north of Grand Teton, and the National Elk Refuge, home of the largest elk herd on earth...
High altitude and steep mountain slopes on all sides of the valley often cause calm winter nights to be very cold, as radiational cooling from snow-covered ground creates cold air near the surface, which then slides down into the valley due to the higher density of the air. In 1993, this effect during an already severe cold snap plunged the morning low temperature down to −56 °F (−49 °C) in the valley, officially recorded by the National Weather Service. The state record low temperature was also recorded in the valley at Moran at −66 °F (−54 °C) in 1933. Summers are warm to mild, due to the surrounding mountains...
