After your landing, you'll be in the Great Glacier. Use your map (press [Square] to view it) to find your way around. You can exit the glacier and return to Icicle Inn by heading south at the big sign or by going through the cave south of the eastern mountain. You'll only be able to wander around the glacier for 1 game hour before you collapse from the cold. Mr. Holzoff will rescue you and bring you to his cabin in the far north. If you want all the items, you'll have to go back into the glacier for them.
In the forest northwest of the southern sign, there are some thick trees in which a Mind Source is hidden.
There's a frozen lake near the center with a Potion sitting on the ice. If you try to get to the middle of the lake, you'll have to jump across some floating ice blocks in a certain patter to reach it. Once you cross, there's a small cave with a Safety Bit inside.
At the hot springs just north of the frozen lake, touch the water.
On the east mountain there's a place where you can choose to go 4 ways: north, northwest, west, and south. Go north and pick up the hard-to-spot Added Cut by the side of the path (it can only be found by heading north from the mountain this way).
In the northwest section of the glacier there's a cave covered with snow in which you'll find an Elixir
In the big windy snowfield where you have to use markers to mark the direction you're traveling, there's a small hut in the middle. Inside is an All.
