The southwest road out of Shoushi eventually leads you to Baishi, but on the way it skirts the base of the odd mountains I call the Snowflake Range. If you keep on straight west after the road turns to the southwest, you'll soon be in the foothills of that range. Careful -- there's a nest of shreth on one of the first foothills you come to, and a cave full of golems on the flatlands just to the south.
