Stuck outside. [spoilerish]

[TragicAngel]

Hi. I've posted a couple of times here before, under the name IdioticAtGaming, but had to change my name due to weird password issues and whatnot. It's no big deal, though, considering that my old name wasn't exactly flattering. Hehe.

Anyway, I'm stuck outside, after getting the lighter and spray can. I understand that I'm probably supposed to make my way back to the bridge control to warm it up/deice it, but can't seem to find a way to make my way back there after the bridge collapses. Any help would be quite appreciated.

If you look inside from the shelter (right after the frozen stone bridge collapsed), look to the left. Walk there. There's few cliffs next to the mountain...

I just stacked some boxes on the remaining ledge and jumped back to the control pad.
I'll try the path next time.

I spent ages trying to stack up boxes and such to get back over after the bridge collapsed. I even went down that slope and stacked boxes there so that they were level with the higher ledge and made a bridge, or at least tried to. Then I noticed the walkway on the left. Then I cried.
