SnowHorn Artifact is an item in Star Fox Adventures. It looks like a golden Alpine Root without the horizontal stripes. Fox can buy it from ThornTail Store for 130 Scarabs (or bargain at 110 Scarabs). The SnowHorn Artifact is the most expensive item sold at the location.
The SnowHorn Artifact must be given to an old SnowHorn in SnowHorn Wastes, who names it the Gold Root. After getting it back, he tells a story how the artifact was stolen years ago, presumably by the ShopKeeper. Then the old SnowHorn gives Fox a chance to prove himself in return. A pad appears from below Fox, and after blowing the Dinosaur Horn on it, a race begins. Fox has to blow the horn on each pad to win access to a Krazoa Shrine.
