3. Devils Tower, Wyoming
This is one of the most stunning natural wonders in the nation and just a brief stop on a trip on Interstate 90 too. This natural rock tower towers 1,267 feet above Wyoming’s Belle Fourche River. It was created by the intrusion of magma into underground sedimentary rock. It is a sacred site to over 25 Native American tribes. You might recognize Devils Tower from the famous film Close Encounters of the Third Kind.
