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.
