The Lewis and Clark Expedition of 1803-1806 systematically recorded weather and climate data during their 4,162-mile journey across largely uncharted territory. This data, organized by date and complemented by route descriptions and 50 color photos and historical maps, creates a fascinating look at the weather-related challenges that, at times, nearly derailed the Corps of Discovery from completing its mission and returning safely. Lewis and Clark is both a compelling read for weather and history buffs and a key resource for scientists researching climate history.

Vernon Preston

Vernon Preston, National Weather Service warning coordination meteorologist in Pocatello, Idaho, marked the beginning of the bicentennial anniversary of the Lewis and Clark Expedition (1803-1806) by compiling the weather and climate data from various expedition journals. The National Oceanic and Atmospheric Administration (NOAA) published this information as a technical memorandum in 2004 and distributed 100 copies. In this volume, the American Meteorological Society has reformatted the data and included explanations of the significance of the expedition's meteorological studies.
