How to open the ice wall?

[Kligan]

There is an ice wall at the middle top tile of Ice Caverns, just south of the blue stairs. It has yeti inside a small room.
How to open that wall? I looked for a lever or anything suspicios nearby, but couldn't find anything.

You break it with a heavy weapon (+ barb crush perk) or fireball it

[UncleIstvan]

You need either a weapon with impact strength 5 (war maul, double axe, halberd, etc.) or fireball to break it.
It's also possible to agro yeti with shooting through the gap in ice while jumping, then he'll break it for you.

Bear Druid right click as well - smashes the ice.

You could start with a joke as an ice-breaker.

I figure there's some way to convince the skeletons to break down this wall. But I tried to do this only once and got hit a lot.
