K-Gr 2 Bauer uses simple sentences and repeated words and phrases to help beginning readers learn about how the Grand Canyon got so grand. A quick introduction to the geology and formation of this natural wonder is followed by a look at what people can do and see while visiting the area. Additional facts are appended. Wallaces watercolor-and-pencil cartoon illustrations are warm and inviting, showing children exploring and enjoying the region.
