Published in 1904, this map shows the routes and interconnecting service of the White Pass and Yukon Railroad between Skagway, Whitehorse, and Dawson City. It includes both train and boat routes, as well as geographical information on the adjacent areas of Alaska, Yukon, and British Columbia. The reverse side of the map contains a timetable as well as vignettes about points of interest throughout the region. The map was made to be folded as a brochure. The map shows the full course of the Yukon River, the longest river in northwestern North America, in both Canada and Alaska. It also records the distance in miles between the maritime port of Skagway and many other localities from San Francisco to remote parts of Alaska and Canada, such as Saint Michael, Caribou, Atlin, and the forbidding Lake Laberge immortalized in the poetry of Robert W. Service (1874−1958). Although the Klondike Gold Rush had ended in 1899, gold was found elsewhere in Alaska, and the White Pass and Yukon Railroad continued to serve the need for a regional transportation system. In the ensuing decades it became a key regional railroad network and eventually an innovator in the containerization of the cargo industry. By the 1950s, the White Pass and Yukon Railroad had pioneered intermodal services, whereby standard containers could be transferred from trains and trucks to ships, and vice versa. This led to a fully integrated network of intermodal transportation that became a model for other companies in the United States, Canada, and across the world.
