Salt samples collected at the Compañía Minera Cordillera mine in the Tarapacá Region of Northern Chile. This mine supplies about 80% of the de-icing road salt to the Boston metropolitan area. The variations in the salt reflect the amount of minerals present in different parts of the mine. These samples were exhibited as part Salt Mountain, an installation based on the journey and processing of the salt from Chile to the streets of Boston.
