Horizontal glaciers are formed when farmers redirect glacier meltwater into channels and pipes, then carefully siphon it off into a series of basins made from stones and earth.
The meltwater enters channels that run downhill, flowing until it reaches a crop site where it bursts forth from a pipe pointing straight into the air.
That is a problem for those who rely on meltwater from them to irrigate their crops: farmers living in the valleys above Leh, in Jammu and Kashmir, for example.
