Situated in the remote desert Pampa, one of the driest deserts on earth, thousands of pampinos lived and worked in this hostile environment, for over 60 years, from 1880, to process the largest deposit of saltpeter in the world, producing the fertilizer sodium nitrate that was to transform agricultural lands in North and South America, and in Europe, and produce great wealth for Chile.
