Publisher's Synopsis
Join in the adventure as Jenna, Caleb, and Ari unlock the secret of time travel and journey back 15,000 years to witness the great Missoula Floods of the Ice Ages--the largest floods to have ever washed over the face of the earth. The time travel kids tour the changing landscapes of this world of the not-so-distant past, when giant mammoths and saber-toothed cats roamed the Pacific Northwest. From back of the mythic Thunderbird, they work together to survive the dangers of the Ice Age Cataclysm!
