    It was just before 8 a.m.on October 17, 2010.She’d checked the higher summits forecast posted by the Mount Washington Observatory before she left.Based on her experience, Bales knew that her hike was realistic.Besides, she had two plans and extra layers of clothing to better regulate her temperature as conditions changed.

At 10:30 a.m., the weather was showing its teeth.Bales added even more layers, including a jacket to protect herself from the cold winds and heavy fog.She made her way across the snow—covered ridge toward Mount Washington and began to think about calling it a day.Then she noticed something:a single set of footprints in the snow ahead of her.She’d been following faint tracks all day and hadn’t given them much thought, because so many people climbed Jewell Trail.But these, she realized, had been made by a pair of sneakers.She silently scolded the absent hiker for breaking normal safety rules and walked on.

Now she felt genuinely alarmed.She was sure the hiker could not navigate(找到方向)in the low visibility and was heading straight toward the challenging trails of the Great Gulf Wilderness.Bales stood there, shocked.The temperature and clouds were in a race to find their lowest point, and darkness was mere hours away.If Bales continued to follow the tracks.she’d add risk and time to the route she’d already adjusted to manage both.But she could not let this go.She turned to the left and called out, “Hello!”into the frozen fog.

Bales wouldn’t get an answer until a week later, when the president of her rescue group received a letter in the mail.It read: “I hope this reaches the right group of rescuers.I want to remain anonymous(匿名的), but I was called John.On Sunday, October 17, I went up my favorite trail, Jewell, to end my life.Weather was to be bad.Thought no one else would be there.I was dressed to go quickly.Next thing I knew this lady was talking to me, changing my clothes, giving me food, making me warmer.
