gr8life, thanks for sharing your story. It's a sorry situation that someone would abandon their partner to descend.
When she dropped her pack, was that 1.9 miles from the summit or from the trail head?
Also, how long did it take you to get to the summit?
Yury is referring to hyponatremia, a condition induced by drinking far too much water without any electrolytes. I guess we should ask how much water did you consume during the hike.
