I am having trouble thinking of why urine would be a better option than snow. If she was already cold, getting colder would have been an issue which may have been her thinking, but I'm still having trouble with urine being a better option. But I wasn't there and certainly wasn't in her head, so it's hard to judge. One thing to consider though is that she did survive; difficult to judge success too harshly.

Google maps, almost as good as no map at all (but that's just my opinion).

Reminds me of an aircrew whose navigator was using a computer printout in lieu of a real navigational chart. They impacted an island not represented on the chart; that was a long time back, but computers are still leaving stuff out.
