Location: This quest takes place in Wetlands. Follow up on Quest: A Dumpy Job.

Shortly: Surveyor Thurdan at Slabchisel’s Survey wants you to retrieve the Thelgen Seismic Record from the Thelgen Rock.

How to: Run a bit northwest and you will see a cave in the hills. This is a pretty annoying cave because its dark and the path is hard to follow. So just follow the left wall and you will find the Seismograph. Upon taking the records (or before) Torrention will spawn and he will drop a Floodsurge Core that will start the Quest: The Floodsurge Core.

The Rewards are 13 silvers and 250 reputation with Ironforge.
