The Warsong Clans lumber-cutting camp, established sometime after the Third War. It is NOT the camp Grom Hellscream built to cut lumber for his warchief, because this camp is far too away from the entrance to the Barrens, and too near the entrance to Azshara. It is likely that the Warsongs built the lumber-cutting camp away from their former lumber-cutting camp, see Warsong Labor Camp, for unknown reasons though, after their leader's death.

IT is much larger than the other camp, and is likely being used for the several small towns and expansions the orcs are making. It also might be away to keep the demons of Felfire Hill penned in between them and Splintertree Post, to prevent threats caused by the Burning Legion.
