Timothy O'Sullivan learned his trade in some of the ugliest places ever captured on film. An employee of famed Civil War photographer Matthew Brady, O'Sullivan shot at Gettysburg and Appomattox, capturing images of mass death and destruction. When the war ended, he was understandably eager to get away from the bloodied East. He signed on to the United States Geological Exploration of the Fortieth Parallel, an expedition led by prominent surveyor Clarence King and tasked with mapping and photographing areas of the Southwest that might appeal to settlers and be suitable for new rail lines.

O'Sullivan brought an old horse-drawn ambulance to use as a darkroom and an artistry to the practical endeavor, carefully framing images of rock spires, waterfalls, and deserts. Though his tin types didn't exactly make Colorado and Utah seem particularly welcoming, they did neatly capture the size of the landscape, the massive scale of its geologic features, and the daily lives of the local Native American tribes. Pleased with the results, the Geological Survey asked O'Sullivan to stay on for a canal-planning expedition to Panama and a tour of the areas west of the 100th parallel, including what would become Arizona and New Mexico.

O'Sullivan's images of the Southwest were among the first seen by the masses back East. O'Sullivan took pains to respectfully pose Hopi tribesmen and document pueblos and canyons alike. The images show an almost empty landscape and the faces of those tough enough to weather its extremes. Unsurprisingly, they were a hit with government types and potential settlers alike, making O'Sullivan famous for the rest of his brief life, which ended on Staten Island in 1882.
