Gr 3-5 –A breathtaking walk through multiple habitats and deep time. Beginning at the banks of the Colorado River, a child and her adult companion hike up the South Kaibab trail from 1.84 billion-year-old “basement rocks” past the layers of the Grand Canyon Supergroup, the Bright Angel Shale, and other major formations to the Kaibab Limestone layer at the top. At the same time, the two pass through riparian greenery, sun-baked desert scrub, and pinyon juniper woodland to reach the South Rim’s ponderosa pine forest. In Chin’s cleanly drawn scenes, viewers who follow along will catch glimpses of characteristic flora and fauna (with other wildlife lined up along the margins) at each elevation, plus clear looks at each distinctive rock layer. Better yet, occasional fossils in the rocks, seen through cutouts, temporarily transport the child with a page turn to prehistoric mudflats, sand dunes, and sea floor. A double gatefold vista vividly underscores Chin’s opening proposition that the canyon is “much more than just a big hole in the ground,” and the author supplements his information-rich running commentary with further notes and illustrations covering the canyon’s history, human settlement, ecology, and geology. It’s all Grand. VERDICT An outstanding introduction to one of the world’s greatest outdoor wonders, with much to offer elementary students about Southwestern biomes, sedimentary geology, and the profound pleasures of observing nature.–John Peters, Children’s Literature ­Consultant, New York City
