This small plastic vile contains dirt from the land in Fonda, New York where Saint Kateri Tekakwitha was first baptized as a Christian back in 1676. Back then, the land was the site of the Caughnawaga Castle, a Mohawk village to which Kateri belonged.
Today, the site is a small, national shrine to honor Kateri Tekakwitha, who was canonized by the Roman Catholic Church on October 21, 2012.
This vile of earth was purchased years ago in the gift shop on site at the shrine in Fonda, New York.
