The Underground Railroad was meant to be a set of secret pathways, and its traces have been obscured by time. But Joyce Hansen and Gary McGowan, who won a Coretta Scott King Honor for their previous book, show how archaeologists and historians sift through corn cobs and root cellars, study songs and quilts, and use the latest technology to reconstruct those heroic journeys. Freedom Roads offers both a fresh look at the escape routes from slavery and an introduction to the tools, methods, and insights of archaeology, anthropology, and historical conservation. Here is a modern-day detective story that uncovers the traces of a time in American history when courageous slaves and idealistic abolitionists defied the law and saved lives.
