In 1898 Thomas Crahan and Robert K. Bonine, who worked for Thomas Edison came to Skagway and filmed a pack train at the Chilkoot Pass. The film shows eight loaded mules led by a man on horseback. Although it is only one minute long, filmed in summer, it is perhaps the earliest movie shot in this area. Seen above is a still from that film. Crahan went on to Dawson and did some filming there and then returned to Whitehorse to film rapids in 1900. The Klondike Exposition Company was organized by Edison and Thomas Crahan to make a filming expedition to the Yukon in order to produce films suitable for display at the Paris Exposition of 1900.
