Lewis and Clark Expedition

"The National Park Service's National Register of Historic Places, Jefferson National Expansion Memorial, and Lewis and Clark National Historic Trail, in conjunction with the National Conference of State Historic Preservation Officers (NCSHPO), proudly invite you to discover the historic places of the Lewis and Clark Expedition. This expedition, which took place between 1804 and 1806, has been described as the greatest camping trip of all time, a voyage of high adventure, an exercise in manifest destiny which carried the American flag overland to the Pacific. It was all of this and more. This travel itinerary highlights 41 historic places listed in the National Register of Historic Places and associated with Lewis and Clark. Many of these places are also part of the National Park Service's Lewis and Clark National Historic Trail."
