Charleston-based photographer Drew Doggett’s recent project, Shadow’s Alight; Portraits of the American West, is the result of 14,000 miles traveled in a 23-foot airstream, visiting 21 national parks. Doggett has spent much his career photographing foreign places and people whose communities are in imminent danger due to development and a lack of conservation efforts. But he wanted to turn his lens toward his own country. In celebration of 100 years of our National Park Service, Doggett set out to capture some of America’s most classic scenes to see how they’ve changed, how they’ve stayed the same, and ultimately why they’re worth protecting. Here, Doggett shares a few favorites from his recent project.
