Two centuries of Lewis and Clark

by William L. Lang

The landscape encountered by the Corps of Discovery during their multi-year, cross- country trek to the Pacific was dramatically different from the one that greeted visitors attending Portland's Lewis and Clark Centennial Exposition in 1905 or the one that exists in the Pacific Northwest today. On the occasion of the bicentennial of the Lewis and Clark expedition and the centennial of the Lewis and Clark Centennial Exposition, the time is ripe for reconciling those earlier events with present-day activities.
