Great Falls Portage is the site on the Missouri River that was an arduous portage site for the Lewis and Clark expedition in 1805. On the upriver trip past the Great Falls of the Missouri the 18 mile portage took 31 days.
It was declared a National Historic Landmark in 1966.
Two separate portions of their portage route are landmarked, and these portions include the lower campsite where boats were taken out, and the upper campsite where the boats were reassembled.
In May, 2008 The National Trust for Historic Preservation listed the site on their list of America's Most Endangered Places.
