Grade 5-7-In 1850, George Davidson was selected by the U.S. Coast Survey office to map America's Pacific coast. During the ensuing years, he and his fellow scientists faced great danger and surmounted numerous difficulties as they doggedly sailed over rough waters and traveled through rugged terrain to record the necessary data. Creating a palpable sense of time and place, Morrison describes the frantic temperament and daunting economic realities of California during the Gold Rush, the difficulties of journeying to and working in remote locations, and the almost-hostile encounters between the explorers and the Makah and Nootka Indians. Cartographic methods are clearly explained through both the carefully researched text and the precise illustrations. In one example, the author relates how the surveyors used telescopes, star maps, and chronometers to determine the exact location of Point Conception. In another, he details how a topographer worked with a plane table and a stadia rod to map the features of Cape Disappointment. Varying between two-page paintings and smaller spot illustrations, the artwork clarifies the text, depicts the breathtaking beauty of the coastline, and adds a sense of adventure. This is an absorbing look at the science of cartography before the era of aerial photography and GPS, and at the dedicated men who risked their lives to chart the unknown.

Gr. 4-8. Morrison, whose previous books include
Buffalo Nickel (2002) and
Civil War Artist (1999), discusses the mapping of the Pacific coastline of the U.S. In the mid-1800s, the U.S. Coast Survey authorized a survey of the west coast, including the land along the coast and the unseen, but sometimes treacherous, land beneath the coastal waters. George Davidson took on the job with little funding but great determination and resilience. As Morrison explains how the surveyors pinpointed locations, distances, and landforms, he points out how modern technology aids in accomplishing the same tasks more quickly and accurately. Combining applied science with history and biography, the discussion follows Davidson and his companions through years of difficulty, danger, and discomfort as they work toward their goal. About three-quarters of the book comprises Morrison's astute and attractive paintings and ink drawings. While the many illustrations suggest a younger audience, their sophistication and that of the text are better suited to older readers. Extensive acknowledgments, a bibliography, and a glossary are appended.
