A rocky green and grey terrain juts and bends its way north to Canada and south to Mexico in the United States’ Northwest region. These are the Rocky Mountains, home to wandering wolverines, majestic elk, and several hundred grizzly bears, whose population is recovering thanks to efforts to reconnect their habitat, allowing them to travel more freely.
Though massive – the largest mountain is almost 4,000m (13,123ft) tall, and the range runs over 4,800km (2,983 miles), the Rocky Mountains are no longer the untamed swath of territory that they once were. Towns and cities have developed in valleys, and highways.
