In this April 29, 2018 photo, a flag and an obelisk mark the Civil War memorial on Hart Island in New York. Over the decades, Hart Island housed a Civil War prison, an asylum, a tuberculosis hospital, a jail and a missile base. Storms and the tides are unearthing the long-hidden bones of Hart Island, creating eerie scenes of skulls, femurs and collarbones on this sliver of land where New York City’s destitute dead have for 150 years been sent off to be unceremoniously buried and forgotten.
