This four-book series of natural history field guides is designed with young readers in mind and is specific to the Rocky Mountain region. The hundreds of full color photographs and dozens of illustrations in each guide make it perfect for children ages 6-12. While it is designed with young readers in mind, each book is packed with concise and intriguing information for the experienced naturalist, as well.
