This is a journal entry:
17 July 2001
We reached our goal this morning at 7 and stood on the peak of one of the highest mountain in the world. We had an awesome view from our vintage point. The whether changed without warning and a heavy snowstorm prevented us from going down the mountain. We pitched tents and waited out the storm.the temperature continued to drop at an alarming rate to 20 degrees below zero. I only hope I would see the morning.
