Chimney Rock has become one of the most famous landmarks in the American West. This unique formation--the most noted on the Oregon Trail--has come to symbolize the greatest voluntary migration in the history of mankind. The site is adminstered by the Nebraska State Historical Society which operates the Ethel and Christopher J. Abbot Visitor Center at the Chimney Rock National Historic Site. The Visitor Center features museum exhibits explaining the westward migration of the nineteenth century and the significant role Chimney Rock had in the memories of those who traveled the trails west. <P>
