I don't remember. I got sidetracked while undergoing a sidetracked quest where I was interested in something that sidetracked me.
I ended up finding a few cool unmarked places on the map between Markarth, Falkreath and Whiterun while just derping around listening to music and getting Grand Souls from Mammoths.
Then I saw two giants walking, so I followed them for the best part of an hour, before eventually getting bored and seeing an opportunity, and I Shouted them off a hill...
