Your hood: pros and cons

New Hampshire Fish and Game said 53-year-old Xi Chen, of Andover, Mass., was attempting a Presidential Traverse, which is around 20 miles long and crosses each mountain in the Presidential Range of the White Mountains.



Chen became severely hypothermic on a trail near Mt. Clay Saturday night into early Sunday morning, prompting what was described as a "high risk rescue" attempt.



Fish and Game officials said Chen texted his wife around 6:30 p.m. to say he was cold and wet and couldn't continue, adding he felt he would die without a rescue.



Rescuers worked to reach Chen despite freezing temperatures, precipitation, and winds gusting over 80 mph.

Rescuers received multiple calls on Saturday for hikers who were cold and wet, the majority in high elevations in the Presidential Range.
