Rancher and Cows, Yukon Territory, Canada, 1978

Photograph by George Mobley

A rancher attends to a mother cow and her calf at the Pelly River Ranch in Canada's Yukon Territory. Life can be hard in this rugged, picturesque territory, where winter temperatures fall to minus 58 degrees Fahrenheit (minus 50 degrees Celsius). A scant 30,000 people call the 186,000-square-mile (482,000-square-kilometer) tract home.
