On Set-Up Day before the Prayer Vigil for the Earth begins, the ground is blessed by a Native American elder and the Sacred Fire lit. These teenage volunteers and their supervisors are from Coesus International School in Washington, DC, and are listening to Bill Rolph, the Prayer Vigil Fire Keeper, explain the meaning of the Four Cardinal Directions and the Sacred Fire and their relationship to the Sacred Circle of structures that form the site of the Prayer Vigil. The structures relate to various Native American and African indigenous and several traditional Western religions.
