World of Warcraft: Cataclysm Archaeology and Cho'gall Profiles

Blizzard's official World of Warcraft website has been updated with information about the new archaeology secondary profession and the ogre mage Cho'gall, both of which will be introduced in the Cataclysm expansion pack. On archaeology:
Archaeology is a new secondary profession introduced in Cataclysm that can be trained along with Cooking, First Aid, and Fishing. After learning Archaeology from the appropriate trainer in a major city, the newly educated treasure hunter will be presented with an Archaeology Journal to track his or her progress, as well as a surveying tool to facilitate discoveries.

The main purpose of Archaeology, of course, is to find artifacts! Artifacts are items lost to history that carry with them a story of the past. While their worth is mainly obtained from the information they impart and the simple joy of discovering them, rarer artifacts represent treasures of sizeable value. Every artifact has an origin, and these origins can be traced back to the races that now inhabit Azeroth and Outland. Research projects are presented in the Archaeology Journal, categorized by the races they're associated with. The fragments needed to complete each research project can be discovered by visiting dig sites.

At any time, players can open their maps and see these dig sites outlined for them across Azeroth and Outland. Upon reaching a dig site, a player can then search for artifact fragments with the survey tool. The survey tool arms the Archaeologist with two unique devices: a telescope and a distance indicator. The distance indicator will change from red to yellow to green as the treasure hunter gets closer, while the telescope will keep pointing the player in the right direction. When the player locates and digs up the treasure, it will provide the Archaeologist with fragments that are collected in the journal. This process will eventually result in a complete artifact.
