In this series, Dawoud Bey imagines the flight of enslaved Black Americans along the final, 50-mile leg of the Underground Railroad through Ohio to Lake Erie, on the other side of which lay Canada and freedom. As a covert network of safe houses and churches, the sites of the Underground Railroad were by necessity secret, and Bey’s landscapes suggest, rather than document, the experience. Photographed by day but printed in shades of gray and black so deep they resemble nocturnes, the prints conjure a darkness at once ominous and protective.
