Danger: Critical comments following!
She should have stopped instead of moving so far
She did not have a signaling capability
She had little to no survival equipment
She separated from her buddy
The positive:
She did keep her head very well
She had skill and confidence
She kept track of direction and had knowledge of the surrounding roads and towns
The environment and weather were in her favor
A small pack with basic equipment and supplies, including signaling, would likely have resolved this in the first day.
