Glaciers sliding across the land caused the valleys and sheer cliffs of the Yosemite. The water that makes up the falls comes from either heavy rains or the melting of high altitude snow. Typically, the falls are gone or reduced to a trickle by summer's end when all the snow is melted and the area is sparse on rainfall.
