The new contested zone uses the same map as the two dungeons I just finished. This isn't a complete map (there's two or three large regions that are uncharted), but it's reasonable for the first half of the zone.
Code:

<ImageStyle Name="exp21_dun_blackhook_contested_1" displayname="Spiral of Vul (Fort Vul)" zonerect="-660, -413, 13, 515">
