Northwind Mine (Skyrim)

Description
Found on the northern front of the mountain range north and slightly west of Riften, the entrance is located shortly east of Mistwatch.

Trekking all the way through the mine and out of the other side leads to Northwind Summit and a battle with a dragon, as well as a new word of power used in the Shout: Aura Whisper.

Also, located inside are three Iron Ore veins.
