Linda Kranz opens her book with the comment, "Rocks are my canvas." In classic picture books such as "Only One You," Kranz has used painted rocks as a means of illustrating books of wonder for children and adults. For decades, the author has collected and photographed one of the earth's marvels: rocks. In this omnibus tribute to the pursuit of the beauty of studying rocks, Linda Kranz notes the great bonus of using rock hunting as a hobby that allows readers of all ages to simultaneously meet up with the great outdoors. Rocks of all shapes and sizes can be found in forests, streams, and even tree roots. She touches on both literacy and science. She urges readers to keep journals about the rock hunting experiences and defines igneous, sedimentary, and metamorphic rocks. Samples of her own journal entries are included. Wisely, she notes places to collect rocks and places to only take photographs. For example, rocks should not be taken from national parks and national monuments. They can be sketched or photographed, but need to be left for others to also discover and enjoy. The photographs that illustrate this wonderful introduction to the art and hobby of rock collecting are superb. This is a rock hunter's bible. The design of the book is great. The end papers are filled with beautiful images of rocks Kranz has collected over several decades and commentaries about the wonders of rocks. One of the interior spreads of note is about rocks her friends have sent her from all around the world. Pictures of some of these rock treasures are superimposed upon a world map. The book is a wonderful compilation of rock collecting by an author and artist who shares a lifetime of loving rocks and appreciating their beauty. In the brief author end note, Linda Kranz invites readers to visit her web site that adds many great extensions to further enrich the education of new rock collectors. This book is a treasure to visit often and to inspire readers to come to realize just how special rocks can be.
