Since the time of Columbus, explorers dreamed of a water passage across the North American continent. President Thomas Jefferson shared this dream. He conceived the Corps of Discovery to travel up the Missouri River to the Rocky Mountains and westward along possible river routes to the Pacific Ocean. Meriwether Lewis and William Clark led this expedition of 1804–6. Along the way they filled hundreds of notebook pages with observations of the geography, Indian tribes, and natural history of the trans-Mississippi West.

This volume covers the last leg of the party's route from the Cascades of the Columbia River to the Pacific Coast, and their stay at Fort Clatsop, near the river's mouth, until the spring of 1806. Travel and exploration were hampered by miserable weather. While in winter quarters, Lewis wrote detailed reports on natural phenomena and Indian life. These descriptions were accompanied by sketches of plants and animals as well as of Indians and their canoes, tools, and clothing.

Gary E. Moulton is Thomas C. Sorensen Professor of American History at the University of Nebraska and recipient of the J. Franklin Jameson Award of the American Historical Association for the editing of these journals.

"The University of Nebraska Press has become the pre-eminent publisher of Lewis and Clark titles, including what is now considered the definitive edition of the journals edited by Nebraska history professor Gary Moulton."—John Marshall, Seattle Post-Intelligencer

"Moulton not only edited the transcriptions of the journal entries; he also provided a detailed index and oversaw a team of consultants who provided expert annotations on botany, zoology, astronomy, archaeology, linguists and medicine. As a result, readers can understand the expedition in its full context. It's no wonder that the series has received many plaudits."—Omaha World Herald

"If you want Lewis and Clark whole, this is the edition to buy. Moulton spent more than two decades pulling the pieces together and did a masterly job."—Anthony Brandt, American Heritage

"For almost two hundred years [Lewis and Clark's] strong words waited, there but not there, printed but not read: our silent epic. But words can wait: now the captains' writings have at last spilled out, and fully, in this regal edition."—Larry McMurtry, New York Review of Books

"The paperback edition, as well made as the original, is a real bargain—and a necessary investment for anyone seeking a comprehensive understanding of the expedition as it played out day by day."—Gregory McNamee, Washington Post Book World
