Forlorn Ridge

The Forlorn Ridge is seemingly a huge long-dead volcano located in southwestern Azshara. It completely dominates the nearby landscape, and both the Alliance and the Horde have built fortifications on the side of the mountain. Many believe it to be the site of the "lost" battleground, Azshara Crater.

You can discover this at.

In Cataclysm
At BlizzCon 2009, it was said Azshara will be the goblin 10-20 starting zone. This subzone will be turned into a strip mine/quarry by the goblins. Azshara Crater will likely never be. Metzen called this subzone "Azshara Crater" confirming the connection.

The strip mine where the Forlorn Ridge used to be is known as the Mountainfoot Strip Mine. Interestingly, a mountain nearly identical to the Forlorn Ridge has been added just north of the former Forlorn Ridge. On this mountain rests the Gallywix Pleasure Palace.

It is stated by Horzak Zignibble, and mentioned twice on a Cataclysm preview for Azshara that the goblins "moved" the mountain. It is possible that they literally moved it north to get at the ore under it.
