Ok, my friend and I found this place in STM. Props to him for originally finding it, so thanks, Steve.
So thats out of the way, lets begin. First, head to Stone Talon Peak. So for hordies, you can fly to Sun Rock Retreat and head North. Alli can fly to Stone Talon Peak. Next, head to "The Talon Den, which is in the Western Part of Stone Talon Peak.
So there we are. Now head north.
The sky is getting brighter, and we keep going straight and then turn left...
Until We see this:
You are not able to walk directly up this, but you can jump to the left, and then back onto your original path. (actual picture has steps that are clearer.) As i believe this was done prior to patch 2.0.1, this is not wall jumping, so it is not difficult to do, directed at those who have trouble wall jumping :P
So now we are here, pretty much self explanatory. Just turn North/Right...
Now we have the choice to go a few different places...
First, to the left is...
Along with this MASSIVE cliff:
To the right is...
And straight is...
I believe that the Alliance has a flight path that goes directly over the last two. Not sure, since I don't play alli
And From the left, you can either jump down the large drop off, or you can go straight/right and kind of follow the mountains to get to the next part. I don't really have a good picture, this will suffice I suppose...
Basically, you will end up here:
And from there, You can go to the Goblin Lumber Mill (as seen when you fly from Zoram'Gar in Ashenvale to Sun Rock Retreat)
This area is really quite large, just about all undeveloped, except a few parts.
I would post more screenies of whats there, but I think you all get the point
Besides, I dont want to ruin any surprises
Last SS showing where we just explored.
Sorry that all these pictures were in thumbnails, thats just how it worked out =/ They save bandwidth i suppose.
Good luck, and enjoy.
