Cameron Walker—National Monuments of the U.S.A.
The 130+ national monuments in the US include a 6-mile wide lake in a volcanic caldera; a riverbed with more than 750 types of fossils, some 44 million years old; homes of many of the nation’s heroes, and sites where historically significant events occurred. Cameron Walker describes them all in National Monuments of the U.S.A., a richly illustrated book for readers aged 6-10 & their families.
