So one of the oldest misc objectives left hanging around in my quest log is to find the power source in shriekwind basin. I decided to try and get my number of misc. objectives down today so I started it and cleared the whole dungeon, by the looks of it, but I'm still having trouble with finding the actual source of power.

I can't find my way around to it, I've been to the very top and killed the vampire master, and then tried jumping down and going all around the dungeon again, but alas I still cannot find where I'm supposed to go.

Anybody able to help me out here? Would be really apreciative.

In the chamber where you kill the Master Vampire - there is a back part and it leads to the Wall with the Shout.

Go back to his chamber and find it there - then you can exit onto a ledge high up the mountain that looks down at Falkreath.
