Stone's sheep are found in North America, particularly in western Canada, including areas like British Columbia and Yukon. They inhabit high-altitude regions like mountains, rocky slopes, and alpine meadows, where they can roam and explore. Stone's sheep are medium to large-sized animals. Adult males, called rams, can weigh around 150 to 250 pounds, while adult females, known as ewes, are generally smaller. Both males and females have distinctive curved horns that can grow up to 4 feet long. Their fur can vary from gray to brown, helping them blend into their mountainous surroundings. These sheep are well adapted to their mountain homes. Their hooves are sturdy and rough, providing excellent grip on rocky terrain. Their keen sense of sight helps them detect predators and danger from afar.

Stone's sheep are herbivores with a diet primarily consisting of plants found in their mountain habitats. They graze on grasses, shrubs, and other alpine vegetation.

Female Stone's sheep give birth to one lamb, occasionally two, after a gestation period of about 6 months. The lambs are born in the spring or early summer, and they quickly learn to navigate their rocky environment. They live in groups called bands, which can include both males and females. During mating season, rams may engage in battles by clashing their horns to establish dominance.

Stone's sheep populations can face threats from habitat disruption and human activities. Conservation efforts focus on protecting their mountain habitats and ensuring the survival of these remarkable mountain-dwelling creatures.
