Judging by the info in the link, she was an experienced hiker - but experienced does not always equate good judgement which was missing on that fateful day.
I agree. I found it very surprising that she decided to "go it alone". Even this time of year, I think the weather on Mt. Rainier is unpredictable.
Seems a bit premature to be accusing her of poor judgement? I have not heard anything about what led to her death, or if the weather played a role. Maybe being with someone would have made a difference, but then again maybe not?
If hiking solo is a crime, then I must plead guilty, your honor. I have done so on many occasions. Sometimes even in unpredictable weather.
