What I Saw in Yellowstone makes it fun for young people to find and identify the park’s most frequently seen plants, animals, geothermal features, and more, whether they are driving park roads, resting at pull-offs, or hiking. The book is packed with color photos, lively descriptions, fun “guess what” factoids, and precise “where-to-see-it” directions. Readers can “check off” what they saw and write notes about when, where, and how they saw it, turning the book into a great journal of their Yellowstone trip to share with friends and classmates back home.
