Iphone was in snow for hours

Hi everyone,

I dropped my iPhone in the snow, the snow plow came right after. I searched for it for hours but could not find it. Finally a few hours after I was able to find it. It's dead, I imagine from how cold it was. I am sure it will have water damage, although it seemed to be mostly caked on ice and snow which I was able to remove. I have not tried to power it on or charge it. It's in a bag of couscous as I type this (we didn't have rice).

I have read online about not turning it on, using rice, etc. Does anyone have any more advice? Any help would be appreciated. Thanks!
