This lesson plan is used to introduce a unit on transportation and how it has changed from 1899 to 2001. It is based on the Harriman Alaska Expedition of 1899, an expedition that used almost every mode of travel available in that time period. In 1899 Edward Harriman assembled a distinguished team of scientists and artists and took them on a two-month survey of the Alaska Coast. In the Harriman Expedition Retraced, scientists, naturalists and artists are observing anew the sites visited by Harriman's scouting parties a century ago.
