Took me about 45 minutes worth of farming the enemies around here. Well worth it, especially since the boars drop the medium hides. I agree with Phantomii, Ironhide does pop in the valley directly north of Echad Sul.
lvl 18 shattertusk. Coordinates are correct; in the valley just north of Echad Sul. Believe maddened shattertusks are placeholder; i killed a lot of em :)
