You've come to the right place if you were looking for the official website of the National Council for the Lewis & Clark Bicentennial. However, the webpage is now in "mothballs," since the mission of the Council has expired. The content will be archived with the Lewis & Clark Trail Heritage Foundation.
Also try the Internet Archives of http://lewisandclark200.org.
Bob Pawloski is maintaining this archive website as a volunteer. Please contact him at bpawloski@cox.net with any questions.
