FOOTPRINT is an experience of the Refinery Corridor Healing Walks, led by Native American grandmothers (Idle No More SF Bay) who live downwind from the Chevron Oil refinery in Richmond, California. After the Chevron explosion of 2012 poisoned their air, they turned to an ancient tradition of healing walks along the oil refineries of the Northeast SF Bay, rallying local communities to reclaim their land and water. We will create a Projection Map of the walk (to project on the side of the UN?) with surround sound installation of the chants/songs and environmental audioscapes of the walk, an immersive experience contrasting the natural world with modern oil industry. Through voices and images of the Walkers we join in their prayer and song for healing, and participate in reclaiming the land. The Map will guide us in to an exhibit that will include photos of these Healing Walk leaders (power of matriarchy) with mini-docs activated via augmented reality that will share personal narratives of the grandmothers. Next year is the fourth and final series of Refinery Healing Walks; this is the last chance to document this transformative event.
