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 at a bargain of 110 Scarabs). The SnowHorn Artifact is the most expensive item for sale at ThornTail Store.
The SnowHorn Artifact must be given to an old SnowHorn in SnowHorn Wastes, who calls it the Golden Root. After getting it back, the SnowHorn tells a story how the artifact was stolen years ago, presumably by the ShopKeeper. The SnowHorn then assists Fox in accessing the nearby Krazoa Shrine.
