Spoiler warning: Plot or ending details follow.

Secret of the Snowy Peaks is a Shrine quest in The Legend of Zelda: Breath of the Wild. The quest is obtained from a diary atop the mountains between Faron Grasslands and Gerudo Desert, and completing this quest grants Link access to Suma Sahma Shrine.

The quest calls for Link to cast a "cold shadow" on a pedestal situated between Mount Granajh and Daval Peak, which is accomplished by holding one of the various snowballs in the area above his head so that its shadow falls across the center of the pedestal while it is active (starting at 16:00 in-game). The Cryonis Rune can also be used to cast a shadow from the small ponds.
