Despite the region being snowy and all surrounding references being the snow versions of the objects, the roads west of Windhelm are using the non-snow versions and look rather out of place. Walking the road from Windhelm, it starts out as snowy and turns into the non-snowy references. The bridge east of Anga's Mill is also a non-snow reference. Finally there is a section of road just east of Fort Dunstad which is a non-snow reference (see attached file for map).
