I think people here are very harsh on the young lady. It's easy to sit in a warm chair with your slippers on and condemn her actions. Have you flown in Wyoming? There is no such thing as flat or low lands there. Even the flat bits are at 5000ft+. There is almost zero radio reception below 10000ft and as mentioned the VOR's don't work well there either. Maybe she didn't have a GPS? Maybe she was taught not to use one, so as to learn the basics, just like most of us were back in the days. Maybe the weather had closed in behind her? Maybe the canyon wasn't wide enough to turn around in, or at least she didn't think she could turn around in it. Unless you've had some mountain flying experience, this is a a real possible scenario. Add to this a rolling mountain gust, and she ran out of options.
Yes, there are multiple things she should have done, but we've al been lost, overworked, stressed out of our minds and been inexperienced. It seems to me like the young lady has a level head and it was because of her good speed management that she walked away from that crash when the inevitable came.
I hope she doesn't stop flying and gets back in the saddle.
