What are the mountains west of Skyrim, that border Hammerfell (near Dragonstar) and High Rock from their eastern view, called?

I recall reading that it's called the Druadach Mountains somewhere.

Hmmmm. The redoubt of druadach thus gave name to the mountain range perhaps? or was it the other way round?

Nevertheless, you have helped me continue in a personal project, so thank you very much.

Dragontail Mtns

Or you could call it The West Reach

The Dragontail Mountains are what frames the Alki'r Desert with the Illiac Bay. I don't think those are the Dragontails.

UESP also says Druadach Mountains, though I'm not sure where that comes from.

It comes from the map that came with Skyrim.
