At the risk of seeming unsympathetic --

As an Alaskan hiker who assumes there is no cell service, this woman appears not to have taken the basic precautions of bringing a compass and a map and the knowledge of how they work with her. Never rely on modern electronic technology when your life depends on it. I personally would not want to ruin the wilderness nature of the Appalachian Trail with a cell phone tower, but more than that, things happen and cell phones can get broken. Maps and compasses always work. And in a pinch, in the Lower 48, you can use an analog watch as a compass ... if you know what you're doing.

Also, as an Alaskan, the mention of Christopher McCandless resonates. That young man was wholly unprepared for what he attempted. He had no business being in the Alaskan wilderness and his failure to use basic commonsense got him killed. Ms. Largay doesn't seem to fall into the same camp of stupidity as McCandless.
