This lesson plan uses Jeremy Anderson’s TODALSIGs system as a basis for teaching students to read, analyze, and draw maps. 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.
