Clouds cast shadow over Gaumukh, the mouth of the Gangotri glacier. In Hindi Gau means cow, and Mukh means mouth, although the origins of the name are unknown. Some speculate it comes from the mouth of the glacier appearing like a cows mouth and some talk about the giving nature of the Glacier which is Holy like the cow providing milk. The flow from the mouth is deep and rapid with large volumes of water shooting out from beneath the glacier. Every year some people die trying to get too close and are crushed to death by huge unexpected collapsing chunks of ice.
