Proposed Site for Lewis & Clark Centennial Expo

This 1902 survey map, of what is now the City of Portland’s northwest industrial district, shows how the Guild’s Lake area looked before it was used as a site for the 1905 Lewis & Clark Centennial Exposition and Oriental Fair. Portland’s wealthy merchants planned the exposition to promote the city to potential investors, immigrants, and tourists. Attracting almost 1.6 million people between June 1 and October 15, 1905, the fair commemorated the cross-country Expedition led by Meriwether Lewis and William Clark in 1804–1806. This map was drawn by engineer William Maxwell.
