The diverted water freezes in winter, and a small glacier is thus formed at a relatively lower height—between 13,000 to 14,000 ft. "Being lower in altitude, generally four or five km above the villages, this melts in spring, just when the sowing season starts," he says. This is particularly useful since the sowing season ends before the natural glacier water begins to flow down. Norphel’s glaciers are about two km long and 150 feet wide with depths ranging from three to 11 ft. They are low cost and require only local labour. Norphel’s first glacier at Phuktse village cost just Rs 19,000. Another one near the Changla Pass is bigger and cost Rs 60,000. So far, Norphel has made about half a dozen such glaciers in Ladakh, using funds from the state’s watershed development programme.
