Members-Only Exhibition Opening March 30th — click here for info.
Exhibition open to public March 31st through April 26th.
This exhibition uses large-scale reproductions of historic maps, photos, and explanatory text to show how America looked before the journey of Lewis and Clark, and what it looked like after. In 1804–06, Meriwether Lewis and William Clark led an expedition from the Mississippi to the Pacific. Their primary goal: to reveal the geography of the West. Using cutting-edge scientific techniques and methods as old as humanity, they created a new portrait of America so persuasive we still recognize it today. This exhibition shows how they did it. The exhibition is free with museum admission.
