Adventuring along the Lewis and Clark Trail : Missouri, Illinois, Iowa, Nebraska, South Dakota, North Dakota, Montana, Idaho, Oregon, Washington / Elizabeth Grossman.

Enhanced descriptions from Syndetics:

When the Louisiana Purchase of 1803 added a vast and unmapped wilderness area to the fledgling United States, President Thomas Jefferson persuaded Congress to fund a "Corps of Discovery" to explore these lands, and he picked a young man by the name of Meriwether Lewis to lead the way. Lewis and his co-command, Captain William Clark, kept journals of the expedition, and what they found amazed the world: three hundred new species of plants and animals, as well as wilderness prairie and mountains previously undescribed. This book is the first guide to contemporary recreational adventures along the route of America's most famous pioneer expedition. It includes abundant natural history, as well as profiles of the many state and national parks to be found in Lewis and Clark country. Author Elizabeth Grossman divides the trail into six sections and recommends ten "explorations" in each, along with many side trips. She offers suggestions for the best day hiking, backpacking, canoeing, kayaking, biking, and wildlife viewing--as well as short, easy walks and car trips to interpretive centers, Native American villages, and scenic vistas. Information on the Corps of Discovery's original campsites is also included, along with excerpts from Lewis and Clark's journals. Though much of the wild lands described in the journals is now gone, travelers can still recognize some of the terrain from these two hundred-year-old descriptions. The present-day adventurer along the Lewis and Clark Trail will doubtless feel a powerful connection with the remaining natural glories that bridge the time from then to now, and will appreciate the opportunity to see this land through the lens of its dramatic history.
