On this page you can view all the bosses and items/loot that they drop in Blackrock Caverns instance/dungeon that became available with the Cataclysm World of Warcraft expansion. Blackrock Caverns is designed as a 5-man instance for players level 80 to 81 and it is located within the Blackrock Mountain close to the old Blacrock Spire instances.
WoWWiki has this to say if you are looking for the entrance to this instance:
Players will need to be level 80 and find the entrance to Blackrock Caverns in order to use the Dungeon Finder for the instance. The entrance is just off of the main ring in Blackrock Mountain on the non-jumping path to Blackrock Spire. Head to the eastern side of the ring to see the summoning stone for Blackrock Spire and follow the path. As it turns north there is a blockade blocking the way. Look right to see the instance line.
