FFOrigins question

I am stuck in Final Fantasy(I) in Origins. I looked at the walkthrough provided on this site, but, sadly, it didn't help. I am trying to get to the Ice Cave. I know that when they made Origins they revamped the world map a bit, could someone tell we where in the devil the ice cavern/cave is? I just end up in the volcano. Am I just blind/lost or what? Help please.

Here you go.

Thank you. Its all so clear when you see the big pic. I'm eternally gratefull. *Bows humbly* :love:

for those who don't know, you can hold start and press circle for the worldmap to appear (easy and normal)
