Throughout the South, vast numbers of African-American gravesites and burial grounds for enslaved persons have been lost or are disappearing through neglect and nature reclaiming the solemn tombstones and markers. Recently, there has been a rise in the restoration and preservation of these forgotten sites by those who have a personal connection with the deceased or an appreciation of their historical significance. But there is much work to be done in order to preserve this part of America's history. UNMARKED not only explores these untold stories of the past but also the efforts underway to preserve them.
