& their Tracks

A beginner-friendly field guide to Mammals of Colorado's mountains and alpine ecosystems

written for visitors to Betty Ford Alpine Gardens

From tiny pikas hiding among alpine rocks to mountain goats navigating steep cliffs, the Rocky Mountains are home to remarkable mammals adapted to life at high elevations.

This introductory guide focuses on 10 mammals native to the Rocky Mountain region, emphasizing alpine and subalpine habitats. Each entry includes a photo reference, identifying features, and clues for recognizing tracks.

Alpine and subalpine mammals

1. American Pika

(Ochotona princeps)

Habitat: Alpine rock fields

Description: A tiny, round-eared relative of rabbits that lives among rocky slopes. Listen for its sharp, squeaky call.

Tracks: Small, furry-footed prints, often in hopping groups. Hind feet land ahead of front feet.

2. Yellow-bellied Marmot

(Marmota flaviventris)

Habitat: Alpine meadows and rocky slopes

Description: A large, stocky ground squirrel with brown fur and a yellowish belly. Often seen sunning itself on rocks.

Tracks: Five toes on hind feet, four on front feet; long claw marks may be visible.

3. Mountain Goat

(Oreamnos americanus)

Habitat: High alpine cliffs

Description: A shaggy white mammal with short black horns and specialized hooves for climbing. Native to parts of the northern Rockies; introduced in Colorado.

Tracks: Two rounded, spreading hoof impressions, often with a broad, blocky appearance.

4. Rocky Mountain Bighorn Sheep

(Ovis canadensis)

Habitat: Alpine cliffs and open slopes

Description: Powerful mountain climbers. Males have massive curled horns; females have smaller, slender horns.

Tracks: Split hooves, generally narrower and more pointed than mountain goat prints.

5. Elk

(Cervus canadensis)

Habitat: Montane and subalpine meadows

Description: A large deer with a tan body and pale rump. Bulls grow impressive branching antlers.

Tracks: Large, elongated split-hoof prints with pointed tips.

6. Moose

(Alces alces)

Habitat: Willow wetlands and subalpine forests

Description: The largest member of the deer family, with long legs, a prominent muzzle, and broad antlers on mature bulls.

Tracks: Very large, elongated split hooves, often spread apart in soft ground.

7. Snowshoe Hare

(Lepus americanus)

Habitat: Subalpine forests

Description: A hare with large, furry hind feet that help it travel across snow. Its coat changes from brown to mostly white in winter.

Tracks: Two large hind-foot prints ahead of two smaller front-foot prints.

8. Red Fox

(Vulpes vulpes)

Habitat: Mountain forests and meadows

Description: A slender canine with pointed ears, a bushy tail, and often reddish fur.

Tracks: Four-toed oval paw prints with claw marks, commonly arranged in a straight travel line.

9. Coyote

(Canis latrans)

Habitat: Mountain meadows and open forests

Description: A highly adaptable canine with gray-brown fur, upright ears, and a narrow muzzle.

Tracks: Four toes, a triangular heel pad, and usually visible claw marks.

10. American Black Bear

(Ursus americanus)

Habitat: Montane and subalpine forests

Description: A powerful omnivore whose coat may be black, brown, or cinnamon-colored.

Tracks: Five toes with a broad heel pad and claw marks; hind prints can resemble a human footprint.

Alpine Animal Tracks

Rocky Mountain Alpine Mammal Tracks - Betty Ford Alpine Gardens

Tracks vary with snow depth, mud, speed, and ground conditions. Never identify an animal from a single unclear print. Protect the wildlife you discover. Observe animals from a safe distance, never feed them, and avoid disturbing sensitive alpine habitats.

Note: These simplified track-pattern sketches, show overall shape rather than provide exact-scale scientific illustrations. These are conceptual silhouettes only.

Beginner tips to identify tracks in the field

  1. Count the toes. Canines typically show four; bears show five.
  2. Look for hoof shapes. Elk, moose, mountain goats, and bighorn sheep have split hooves.
  3. Study the pattern. Hares and pikas hop, while foxes and coyotes often walk in relatively straight lines.
  4. Check the surroundings. Elevation, habitat, and signs such as scat or feeding marks can help narrow identification.
