Colorado’s Raggeds Wilderness—named for peaks like Marcellina Mountain—turns to gold in autumn. The wilderness covers nearly 65,000 acres (26,000 hectares) of the White River and Gunnison National Forests. It includes some of the world’s largest stands of fast-growing aspen trees, which can gain 5 feet (1.5 meters) in a year.
