A friend of mine, Dale Wagner, PhD, is the lead investigator on a follow-up study of altitude illness on Whitney. He did the first part last year, on the summit.

This part will probably be the largest study that has been done on the subject. The study will go from July 29 to Aug 13. I will be assisting from July 29 to Aug 4, when I must return to LA.

We will be stationed at the trailhead sign, and if you will be in the area, please stop and say "hi", and if you are giving a try at the mountain, please take the 10 minutes to complete the survey. This is designed to further understand this malady, and to be able to better advise people how to best make their attempts in the future!
