Francisco Seufferheld and Jeannine Koninckx lead marketplace literacy educational programs in Argentina for the Subsistence Marketplaces Initiative in the College of Business. Early in 2016, they will lead a different sort of experience -- an expedition to look for signs of life in the highest lake in the world. The lake is near the summit of Ojos del Salado, the world's tallest active volcano, and is the only place on Earth at this altitude with liquid water. Read more about the adventure here.
