Cataclysm Dungeon Entrance Locations

[Waldonnis]

One change introduced in Cataclysm is the requirement that you find dungeon entrances before you can queue for them in the dungeon finder. This only applies to Cataclysm-specific dungeons, so don't panic and think your new goblins will need to trek out to Gnomer or anything! Below is a list of the release dungeons and a short description of where to go to find the entrances (descriptions courtesy of the many posters in the beta forums). I'm not including raid instance entrance locations at this time, but may fill those in later.

• Blackrock Cavern (Searing Gorge/Burning Steppes)
  Inside Blackrock Mountain, between Searing Gorge & The Burning Steppes. Follow the circular pathway to the lowest Eastern side entrance(next to the Meeting Stone), go inside and take first right.
  
• Throne of the Tides (Vashj'ir)
  On the Eastern edge of the Abyssal Shelf in Vashj'ir, follow the center of the Whirlpool down into a Chamber below which contains the instance entrance.
  
• The Stonecore (Deepholm)
  After going to Deepholm, follow the Temple of Earth up it's Western side. You'll find a meeting stone on a balcony, with the entrance to The Stonecore behind it.
  
• Halls of Origination (Uldum)
  To the lower right on the map there is a pyramid. The entrance is inside.
  
• Lost City of the Tol'vir (Uldum)
  Bottom Center on the map there is a village built in the delta of the river. The entrance is in the northern part of the village.
  
• Vortex Pinnacle (Uldum)
  Bottom right on the map. Fly there and look in the sky, you cant miss it.
  

Additionally, one of the beta participants made a similar list with pictures to make the locations clearer, so if the above descriptions aren't good enough, feel free to visit their site (CLICKY).
