Book excerpt: An indispensable guide to our nation's epic adventure The years 2003-2006 mark the bicentennial of Meriwether Lewis and William Clark's famous transcontinental journey between the Missouri and the Columbia River systems. They never did find the fabled Northwest Passage, but over twenty-eight months, the Corps of Discovery traveled more than eight thousand miles through eleven future states, named scores of places and rivers, met with many Native American tribes, and wrote the first descriptions of heretofore unknown plants and animals. By the end of their trip, Lewis and Clark had navigated and named two thirds of the American continent. They may have had undaunted courage, but the sheer volume of information related to their expedition can be more than a little daunting to the armchair historian. Written by two highly regarded Lewis and Clark experts, this book contains over five hundred lively and fascinating entries on everything from the members of the expedition and the places they went to the weapons and tools, trade goods, and medicines they carried, along with the food and amusements that sustained them. Highly readable and informative, it's the perfect introduction for the Lewis and Clark novice, and the comprehensive guide no buff will want to be without. "This handy volume, timed for publication as the bicentennial of the Lewis and Clark expedition opens, has the virtue of teaching the student while helpfully reminding the scholar.
