Discovery Online’s Wayback Machine takes visitors on a virtual trip back in time to 1848 and the California Gold Rush. You’ll meet the figures who shaped the era through authentic drawings and photographs and listen to them tell their stories through sound files. At the end there’s a list of links to other journeys in the Wayback series, such as the Battle of Antietam and the Brinks robbery.
