Snowpeak

Snowpeak is a location from The Legend of Zelda: Twilight Princess. Located in the Peak Province north of Hyrule, it is a mountainous region of extreme cold. Yetis inhabit the mountains, but only two are encountered in the game.

Overview
Snowpeak consists of several mountains. During the Twili invasion, Snowpeak's cold weather was responsible for freezing Zora's Domain, in result rendering Lake Hylia to be with little water. The only entry to the Snowpeak is through Zora's Domain, located in the Lanayru Province.

Relevance to the story
After Link and Midna discover that the Mirror of Twilight is in pieces, the Ancient Sages indicate that one of the shards is located in the Snowpeak Ruins. Shortly after this, Ashei is found in the bottom part of Snowpeak. She relates to Link that a monster (who turns out to be Yeto) has been constantly invading Zora's Domain, stealing Reekfish. She then hands over a sketch of the "monster" to Link, hoping he can do something about it. Link finds Prince Ralis in Kakariko Graveyard and reveals to him the sketch and the tale. After this, Prince Ralis provides Link with the Coral Earring, a special lure which attracts Reekfish, the only known one of it's kind. Link then uses the Earring with the Fishing Rod to pull in the fish and then in wolf form, uses his olfactory senses to recognize the smell of the Reekfish.

Now with knowledge of the scent, Link trails the stench of the fish through the trails and caves of Snowpeak, ultimately locating Yeto. Unable to converse sensibly with Yeto, Link attempts to find a way to the Mirror shard and rolls into a tree, causing a frozen leaf to plummet down into the snow. Yeto takes this as a hint to race him down Snowpeak, and they both cascade down the mountain, eventually reaching Snowpeak Ruins, the mansion where Yeto lives and the location of the Mirror Shard.

After the Mirror Shard is recoverd from Snowpeak Ruins, Yeto and his wife Yeta are found on the top of Snowpeak. They both offer to race Link to the Snowpeak Ruins and gives him a Piece of Heart when he beats both of them.
