Kema Kosassa Shrine
The Kema Kosassa Shrine is located within the Risoka Snowfield at the far western end. The region surrounding the shrine is bitterly cold, requiring Link to wear armor with Cold Resistance, such as the Snowquill Set, in order to survive.
The shrine's travel gate provides access to the Gerudo Highlands by uncovering the hot air vents close to the rock outcrop overlooking the snowfield, as well as to the Statue of the Eighth Heroine to the north.
It's the only shrine in the Highlands that has no prerequisites to uncover, as other shrines are bound by shrine quests (Keeha Yoog Shrine), covered in ice (Kuh Takkar Shrine), or require DLC to access (Kihiro Moh Shrine).
