In these ways, among others, the Rocky Mountains are truly a natural wonder! Readers find out the combination of ways the mountain range formed as well as where to find the highest peaks in this book. Accessible language and age-appropriate detail are complemented by full-color photographs of the majestic Rockies as well as a map showing the range's location in North America.
