"With exceptional clarity of text and unusually appealing pictures, the geologic concept of mountain building is presented for young readers. Two stories parallel each other perfectly, and the line of Elizabeth's small sand mountain in the inset pictures flows seamlessly into the contours of the larger mountain."--The Horn Book

"Spectacular paintings reinforce the basic geological concepts presented in this story."--American Bookseller

"An attractive, mind-expanding book."--Kirkus Reviews
