In 1804 Meriwether Lewis and William Clark led an unprecedented overland expedition across North America and back, pioneering the western exploration and expansion of the United States. Two centures later, photographer Greg MacGregor retraced their journey to see the present state of this historic route. This exhibition features 60 of MacGregor's dramatic black-and-white images chronicling the transformation of the American landscape. Paried with the images are entries from the Lewis and Clark journals, which MacGregor used to follow in their footsteps, and maps of the expedition trail.
