HOW TO MAKE A MOUNTAIN

From rock to mature mountain in nine steps—and millions of years!

An engaging raccoon narrator, a companion woodpecker, and a girl with medium brown skin and puffy ponytails guide readers on a challenging mountain-making journey. First, readers must find a “supercolossal” rock and push it into another giant rock so that it will “crumple into folds,” as happens in the process known as continental collision. Other steps include carving waterways, creating an alpine glacier that will sculpt the mountain and its valleys, melting the glacier, forming mountain soil, adding plant life, and introducing animals. Object lessons using familiar items and hands-on activities make the narrative accessible. The text uses comparisons to aid comprehension: Tectonic plates “move about as fast as your fingernails grow.” Pencil, gouache, and digital artwork in soft earth and forest tones shows a mountain forming page by page. Some illustrations, like a double-page spread showing how vegetation varies according to altitude, serve as friendly annotated diagrams. Making a mountain is hard work, but the raccoon guide sprinkles topical humor throughout. An unexpected encounter with a crocodile ancestor in the Arctic adds interest. The final step is all about enjoying the mountain and protecting it through stream cleanups, trail maintenance, and hiker education. The backmatter includes a glossary of mountain features.
