In the creation kit the Notched Pickaxe has the editor ID: dunVolunruudPickaxe. Meaning it was originally supposed to be found inside Volunruud.

It is likely that I started out only as a reference to Notch and Minecraft but then they decided to move it to the Throat of the World to reference Irvine and Mallory as well. And Easter Egg doesn't have to be about one thing, they can reference two things at the same time.
