Black bear
Order: Carnivora, Family: Ursidae

Occurrence: Forests, slide areas, alpine meadows - C

The American black bear (Ursus americanus) is North America's smallest and most common species of bear. It is a generalist animal, being able to exploit numerous different habitats and foodstuffs. The American black bear is listed by the IUCN as least concern, due to the species widespread distribution and a large global population estimated to be twice that of all other bear species combined.

Bobcat
Order: Carnivora, Family: Felidae

Occurrence: Open forests, brushy areas - C

The bobcat (Lynx rufus) is a North American mammal of the cat family, Felidae. With twelve recognized subspecies, it ranges from southern Canada to northern Mexico, including most of the continental United States. The bobcat is an adaptable predator that inhabits wooded areas, as well as semi-desert, urban edge, forest edges and swampland environments. It persists in much of its original range and populations are healthy.

Cougar
Order: Carnivora, Family: Felidae

Occurrence: Coniferous forests - C

The cougar (Puma concolor), also known as puma, mountain lion, mountain cat, catamount or panther, depending on the region, is a mammal of the family Felidae, native to the Americas. This large, solitary cat has the greatest range of any large wild terrestrial mammal in the Western Hemisphere, extending from Yukon in Canada to the southern Andes of South America. An adaptable, generalist species, the cougar is found in every major American habitat type. It is the second heaviest cat in the American continents after the jaguar. Although large, the cougar is most closely related to smaller felines.

Coyote
Order: Carnivora, Family: Canidae

Occurrence: Forests, grasslands - C

The coyote ( or ) (Canis latrans), also known as the American jackal or the prairie wolf, is a species of canid found throughout North and Central America, ranging from Panama in the south, north through Mexico, the United States and Canada. It occurs as far north as Alaska and all but the Arctic portions of Canada.

Elk
The subspecies Roosevelt elk (Cervus canadensis roosevelti) occurs in the park. Order: Artiodactyla, Family: Cervidae

Occurrence: Open forests, meadows - C

The elk, or wapiti (Cervus canadensis), is one of the largest species of deer in the world and one of the largest mammals in North America and eastern Asia. In the deer family (Cervidae), only the moose, Alces alces (called an "elk" in Europe), is larger, and Cervus unicolor (the sambar deer) can rival the C. canadensis elk in size. Elk range in forest and forest-edge habitat, feeding on grasses, plants, leaves, and bark.

Mountain goat
The mountain goat is an introduced species within the park. The park and Forest Service are undertaking projects to relocate mountain goats to the Cascade mountains. Order: Artiodactyla, Family: Bovidae

Occurrence: High peaks and meadows - CL, I

The mountain goat (Oreamnos americanus), also known as the Rocky Mountain goat, is a large-hoofed mammal found only in North America. Despite its vernacular name, it is not a member of Capra, the genus of true goats. It resides at high elevations and is a sure-footed climber, often resting on rocky cliffs that predators cannot reach.

Mule deer
The black-tailed deer sub-species (Odocoileus hemionus columbianus) is found in the park.

Order: Artiodactyla, Family: Cervidae

Occurrence: Open forests, meadows, often at high elevations - C

The mule deer (Odocoileus hemionus) is a deer whose habitat is in the western half of North America. It gets its name from its large mule-like ears. Adult male mule deer are called bucks, adult females are called does, and young of both sexes are called fawns. The black-tailed deer is considered by some a distinct species though it is classified as a subspecies of the mule deer. Unlike its cousin, the white-tailed deer, mule deer are generally more associated with the land west of the Missouri River. The most noticeable differences between whitetails and mule deer are the color of their tails and configuration of their antlers. The mule deer's tail is black tipped.

Gray wolf
Although native to the park, the gray wolf was extirpated from the park in the 19th century.

Order: Carnivora, Family: Canidae

Occurrence: Coniferous forests - E

Northwestern wolf is a subspecies of a gray wolf or grey wolf (Canis lupus), often known simply as the wolf which is the largest wild member of the family Canidae. It is an ice age survivor originating during the Late Pleistocene around 300,000 years ago. DNA sequencing and genetic drift studies reaffirm that the gray wolf shares a common ancestry with the domestic dog (Canis lupus familiaris). Although certain aspects of this conclusion have been questioned, the main body of evidence confirms it. A number of other gray wolf subspecies have been identified, though the actual number of subspecies is still open to discussion. Gray wolves are typically apex predators in the ecosystems they occupy.

Red fox
The red fox is an introduced species within the park.

Order: Carnivora, Family: Canidae

Occurrence: Grasslands, open forest - R, I

The red fox (Vulpes vulpes) is a small canid native to much of North America and Eurasia, as well as northern Africa. It is the most recognizable species of fox and in many areas it is referred to simply as "the fox". As its name suggests, its fur is predominantly reddish-brown, but there is a naturally occurring grey morph known as the "silver" fox. The red fox is by far the most widespread and abundant species of fox, found in almost every single habitat in the Northern Hemisphere, from the coastal marshes of United States, to the alpine tundras of Tibetan Plateau.
