The common name, Dall's sheep or Dall sheep is often used to refer to the nominate subspecies, O. d. dalli. The other subspecies, O. d. stonei, is called the Stone sheep. Originally, the subspecies O. d. dalli and O. d. stonei were distinguished by the color of their fur. However, the pelage-based designations have been shown to be questionable.
These sheep are about 1.5 m high and can weigh up to 110 kg. The female sheep have small, tan horns and the male sheep have larger horns that become more twisted as they age. The wool of Dall's sheep is almost pure white. [5] The sheep's horns grow fastest in warm weather and slowest in cold weather. This puts rings in the horns called annuli.
Sheep Mountain is a 1,953-metre (6,407-foot) mountain summit of the Saint Elias Mountains, in Kluane National Park of Yukon, Canada. It is known as Thechàl Dhâl by the Southern Tutchone people, meaning "Skin Scraper Mountain", referring to the thechàl, a flat stone scraper that was used to prepare animal hides. [ 3 ]
Pelage colour variations range widely, from slate grey-brown with a white rump patch, dark tail and white on the inside of the hind legs, to an almost completely white/grey-white coat with a dark or black dorsal surface on the tail. Horns are curved in form and vary in colour from a yellowish-brown to dark brown horns.
Wildlife including elk, moose, mule deer, bighorn sheep, black bears, and cougars inhabit its igneous mountains and glacial valleys. Longs Peak, a classic Colorado fourteener, and the scenic Bear Lake are popular destinations, as well as the historic Trail Ridge Road, which reaches an elevation of more than 12,000 feet (3,700 m).

Bighorn sheep inhabit alpine meadows, grassy mountain slopes, and foothill country near rugged, rocky cliffs and bluffs. [8] Since bighorn sheep cannot move through deep snow, they prefer drier slopes, where the annual snowfall is less than about 150 cm (60 in) per year. [8] A bighorn's winter range usually has lower elevations than its summer ...
Higher elevation have Dall sheep (Ovis dalli) and, in the south, Rocky Mountain goat (Oreamnos americanus). Polar bears ( Ursus maritimus ) are found on the Arctic coast. The mule deer ( Odocoileus hermionus ) and its predator, the cougar ( Puma concolor ), are becoming increasingly common in the south, and coyotes ( Canis latrans ) are ...
During the following four consecutive expeditions in the valley Jean Poirel discovered more than 250 caverns. The most important contained 116 Dall sheep's skeletons (carbon-14 dated to 2500 years BC); Jean Poirel named it "Valerie Cavern" after his daughter. He took topographic notes and drew detailed maps, paving the way for the park's creation.
