In competition for a mostly unclaimed continent, Spanish, English, Dutch, French and Portuguese explorers guarded their maps as state secrets, as knowledge of the landscape was the key to acquisition. Though technically innacurate and incomplete, the early maps reveal active imaginations.

Maps of the original Lewis and Clark expidition with modern towns lon/lat. Indian villages, cabins, forts, 225 campsites, rivers, terrain features, all in beautiful color, print out as large as you like. Made to scale as the original, 64 in all. Created in word. Can be played like a boardgame

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.

A beautifully rendered reference guide to the Great Plains portion of the famous expedition through the American West highlights the explorer's remarkable encounters with previously undocumented flora and fauna as they moved through the Plains region. Original. (Biology & Natural History)

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.

Particularly valuable for Ronda's inclusion of pertinent background information about the various tribes and for his ethnological analysis. An appendix also places the Sacagawea myth in its proper perspective. Gracefully written, the book bridges the gap between academic and general audiences.OCo"Choice""

For Before Lewis and Clark, A. P. Nasatir translated and annotated 239 documents relating to the history of the exploration of the Missouri River through 1804, when Lewis and Clark began their ascent of the waterway. The value of this collection is in the range of documents Nasatir included, some of which are unavailable elsewhere. The volume also includes seven maps; two facsimile illustrations; and an excerpt from the journal of Jean Baptiste Truteau, the Canadian-born explorer whose record of his 1794-95 travels proved valuable to Lewis and Clark. This edition marks the fiftieth anniversary of the first publication of Nasatir’s landmark document collection. Five fold-out maps omitted from the most recent paperback edition have been restored for this one-volume edition.
