I really didn't expect to get much out of a children's picture book on rocks. Rocks are, well, rocks! I was wrong. Mrs. Kittinger has done a fine job in presenting various types of rock, how they are formed in nature (with a significant emphasis on volcanoes) and the various fascinating and often beautiful varieties of rocks. There are many stunning photos and fascinating statistics on rock-related items from Mount Rushmore (and it's lesser known "sister-sculpture" – Stone Mountain – of some "monumental" figures of the Confederacy) to the Grand Canyon to amazing volcano formations. The book also includes a glossary, an index, suggestions for further reading and internet resources for rock collectors.
