Lewis and Clark's Expedition from the Mississippi River to the Pacific Ocean was the first governmental exploration of the "Great West." The history of this undertaking is the personal narrative and official report of the first white men who crossed the continent between and British and Spanish possessions.

Many aspects of the Corps of Discovery's epic journey across the United States and back are well known- how President Thomas Jefferson gave a mandate to Meriwether Lewis in 1803 to explore the continent from the Missouri River to the Pacific Ocean; how Lewis chose his good friend William Clark to be his companion in leadership; how Sacagawea, a young Native American mother with a newborn child, joined the expedition by chance and was instrumental to its success; how everyone had long since assumed the explorers were dead by the time they retuned in the fall of 1806. But do you know the whole story? It Happened on the Lewis and Clark Expedition gives readers inside information on the Corps of Discovery's awesome feats and accomplishments as they traveled into the unknown and mapped a route across the vast western territory of the United States. Did you know that the expedition had a deserter during its early days? That before the arrival of Lewis and a band of men, the Shoshone had never seen whites: or that Seaman, the giant Newfoundland who was part of the team and an honored pet, made it all the way to the Pacific and back? Enjoy these stories and more as author Erin H. Turner, in an easy-to-read style that is entertaining and informative, recounts captivating moments from our nation's early history.

When Meriwether Lewis, William Clark, and the "Corp of Discovery" left St. Louis, Missouri, on May 21, 1804, their mission was to explore the vast, unknown territory acquired a year earlier in the Louisiana Purchase. The travelers hoped to find a waterway that crossed the western half of the United States. They didn't. However, young readers will love this true-life adventure tale of the two-year journey that finally brought the explorers to the Pacific Ocean.

ANNOTATION: In Discovering Lewis and Clark from the Air, aerial photographer Jim Wark and Lewis and Clark scholar Joseph A. Mussulman offer a fascinating new perspective on the Corps' historic journey. From Monticello in the east to Fort Clatsop on the Pacific coast, the wild continent the expedition crossed is revealed anew in breathtaking full-color photographs. Well-researched text accompanies each photo, including quotes from the explorers' journals. The view from above provides new information about the Corps' experience and stirs fresh wonder at their achievement.

One of the greatest challenges faced by William Clark and Meriwether Lewis on their 1804?6 Corps of Discovery expedition was that of medical emergencies on the trail. Without an attending physician, even routine ailments and injuries could have tragic consequences for the expedition?s success and the safety of its members. Of these dangers, the most insidious and potentially devastating was the slow, painful, and oftentimes fatal ravage of venereal disease. ø Physician Thomas P. Lowry delves into the world of nineteenth-century medicine, uncovering the expedition?s very real fear of venereal disease. Lewis and Clark knew they were unlikely to prevent their men from forming sexual liaisons on the trail, so they prepared for the consequences of encounters with potentially infected people, as well as the consequences of preexisting disease, by stocking themselves with medicine and the latest scientific knowledge from the best minds in America. Lewis and Clark?s expedition encountered Native peoples who experienced venereal disease as a result of liaisons with French, British, Spanish, and Canadian travelers and had their own methods for curing its victims, or at least for easing the pain it inflicted. ø Lowry?s careful study of the explorers? journals sheds new light on this neglected aspect of the expedition, showing in detail how sex and venereal disease affected the men and their mission, and describes how diverse peoples faced a common threat with the best knowledge and tools at their disposal.

Few events in American history have shaped the nation like the Lewis and Clark Expedition. It opened the American West for settlement. It redrew the map of the United States. It identified an array of native peoples, spectacular places, fascinating creatures, and extraordinary flora unknown in "civilized" America. It defined the American nation as a land stretching from coast to coast-and it launched the spread of population in a mighty frontier migration unlike anything ever witnessed in America before or since. Lewis and Clark on the Trail of Discovery contains 19 chapters, detailing the expedition chronologically. A "museum in a book," this fascinating volume contains re-creations of original documents such as diary entries, letters, maps, and sketches-all meticulously reproduced so that the reader can actually handle and examine them. Among the documents included in the book are: The actual letter of credit Jefferson wrote to Lewis committing the U.S. government to pay for the expedition. The code Thomas Jefferson provided to Lewis for sending secret messages. Clark's sketch of the technique some Indians used to flatten their heads, a sign of prestige. Clark's letter of gratitude to Sacagawea, a Shoshone teenager who helped the expedition. A newspaper account of the expedition's return to St. Louis.

The diaries and personal accounts of William Clark, Meriwether Lewis, and other members of their expedition chronicle their epic journey across North America in search of a river passage to the Pacific Ocean and describe their encounters with the Native American peoples of the West, exotic flora and fauna, and amazing natural wonders.
