Meet the porters of Nepal, who work long days, sometimes even weeks, transporting baggage and materials around the steep, mountainous terrain of the Khumbu region. Being a local porter, some of whom belong to the Sherpa ethnic group, is a tough, thankless job, especially outside of the more coveted jobs in the tourist trade. Some begin transporting materials around the mountains as teens, and many are forced to continue because of a lack of other opportunities.
