I hate this zone with a passion every time it comes up as a level 40 hotzone. Very difficult to find anything if you aren't one of the three tracking classes.
Found 5/5 of these south of City of Mist and West of the Trakanon's Teeth zone. If you don't see any up when you first roll in just stand there and kill everything that comes in range. You'll get your kills and be on your way.
