To combat receding Himalayan glaciers caused by man-made climate change, Indian Chhewang Norphel has been building his own glaciers.
Here, Norphel is using what is abundant — stone — to conserve what is precious — water. The idea is simple: Divert the unneeded autumn and winter runoff into a series of large, rock-lined holding ponds. As the days grow colder, the ponds freeze and interconnect into a growing glacier. He has built 10 glaciers across the region. His largest stretched more than a mile before an unusual week of rain wiped it out in 2006.
Norphel says that a good artificial glacier costs about $50,000.
