You can even see the super-secret hidden thingie from the cave entrance!
The tomb of Khunzar-ri!.. Yes, I remember I looked at the same spot too, but I can't understand what do you mean. You mean, we could possibly reach this place from there since it exists?
Quite a few "long lost", secret underground places in game also have giant holes in the cavern ceiling exposing the secret to the surface. One could just be out on a stroll, come across the giant holes in the ground, look down and see the big secret. Hence, not being very secret.
