Book excerpt: New Mexico's harsh terrain, countless wars and epidemics were a challenging and fascinating environment for the many cultures and peoples who settled there. When tragedy struck, their faith and religious rituals allowed them to mourn, celebrate and commemorate their dead. From Pueblo Indians and Spanish colonists to Jewish immigrants and American veterans, many old traditions have endured and blended into modern society. The area is also home to many unique death sites, including the graves of Smokey Bear and Billy the Kid, and the largest contemporary collection of human bones in the world. Author Ana Pacheco guides you through the history of Christmas death rituals, roadside descansos, communal smallpox graves, Civil War memorials and more.
