Adaptions of the

Bighorn sheep have lived through many different environments and still continue to thrive.

Bighorn sheep know their terrain.
Rocky Mountain bighorns do not migrate during the winter months like many animals. Instead they tough it out, reducing the number of predators they encounter.
Because of the harsh conditions of the Rockies, bighorns develop a thick layer of course hair over their usual coat in the winter. During June and July, molting takes place, losing their thick outer coat in patches.
The acute eyesight of bighorns allows them to see a mile away. This is useful for spotting predators or finding hiding spots if being hunted.
Although bighorns are not predators and cannot defend themselves, their sheer muscular anatomy makes them a tough animal to kill. Being in top physical shape also allows them to run at high speeds (20+mph) for long durations if being hunted.
Although bighorns do combat for dominance, they do not kill each other. They travel in herds, reducing the chance of a particular bighorn being killed.
The hooves of a bighorn are perfectly designed for the terrain. Each hoof is separated into halves, conforming to fit even the slipperiest of mountainsides. The inside of the hoof, being cushioned, allows them to keep their balance on uneven surfaces.
Bighorn sheep are not susceptible to hyperthermia. Being excellent swimmers, bighorns are often around water. They normally have an internal body temperature of 101°F, but can tolerate temperatures up to 107°F.

Many predators, including the fox, have forward facing ears and eyes to focus on their prey. T
They have acute hearing and a keen sense of smell.
Their eyes are quick to detect movement but do not see stationary objects so well.
Prey, such as mice, are detected by sound.
The fox will leap on the spot the sound comes from, pinning the prey with its forepaws.
The fox has large canines to enable it to seize and stab prey.

The presence of a sand verbena at 7,700 feet elevation in the northern
Rockies is unexpected, as most members of this North American genus occur in the Southwest or along the Pacific Coast.
One speculation by botanists is that the warmth provided by the geothermal activity in the area enabled a genus which had evolved in a warmer climate to gradually adapt to conditions in Yellowstone.
Today, Yellowstone sand verbena tolerates the long, cold winters and uses the brief summer to bloom and reproduce.

white pine, pitch pine,scrub pine, and creeping pine,[2] occurs in the mountains of the Western United States and Canada, specifically the subalpine areas of the Sierra Nevada, the Cascade Range, the Pacific Coast Ranges, and the Rocky
Mountains from Wyoming through the Continental Ranges. It shares the common name creeping pine with several other "creeping pine" plants.
The whitebark pine is typically the highest-elevation pine tree of these mountains, marking the tree line.
Thus, it is often found as krummholz, trees dwarfed by exposure and growing close to the ground.
In more favourable conditions, trees may grow to 20 meters (66 ft) in height, although some can reach up to 27 meters (89 ft).
