When I used to own Zelda 2 on my NES, I always figured that area must have held some sort of secret because it just felt gratuitous.
Fast forward a decade and a half, and I found out the truth while reading essays on Hyrule Geography at
www.zeldalegends.net">Zelda Legends. Of course, Spectacle Rock is way too large compared to the rest of the area, but I guess it was the only way to make it recognizable.
