Of all the large animals on exhibit at the Wildlife Safari in Winston, Oregon, the Roosevelt elk’s natural habitat is probably the closest because they live in the Pacific Northwest forests. A herd of 5,000 is at the Olympic National Park in Washington state. The park was created by President Roosevelt in 1909. This gorgeous female elk, also called a cow, can weigh around 600 pounds and live 12 to 15 years in the wild. In protected facilities such as Wildlife Safari, an elk can reach their 25th birthday.
