Yesterday my father and I set out for a "day" hike of Whitney. We stopped at Lone Pine Lake to nap and hopefully further acclimate before our Midnight permit became active.
Both of us felt great as we began our trek. At some point I began to complain of a very mild head ache. I was being careful to hydrate, had hiked a ton this summer and am in very good shape and I hoped the nights stay at about 8,000 feet after my flight from Alaska would be enough to acclimate. My dad and I also hiked Dana last year and had no effects.
Well at some point my headache worsened and I felt a little nauseous. We made it to Trail Camp under a gorgeous Full Moon that was literally blinding in its brightness. At this point, 12,000 ft. I knew my summit effort was in jeopardy. I took some aspirin, we rested a bit, and then headed up the 97 swithbacks. Not long after (maybe 200 ft. Elevation) I made the call. The nausea was scaring me and I had never experienced altitude sickness. About 10-15 minutes and heading down the nausea overcame me and I violently vomited including dry heaves (sorry to be so graphic but I am hoping others can learn or give advice). At this point the headache was massive and to be frank I was VERY scared. Thoughts of rescue were dancing through my head and it was still dark. All I could think of at this point was advice I've read to get down! So I rushed down as much as I could. Several times the headache, fatigue and nausea would overcome me and I would find a place to almost lay down on the trail. I was also cold and stopping too long I would tremble with shivers. I never did vomit again but I believe I fell asleep a few minutes several times on the way down. I was also doing my best to stay hydrated but the taste of water digusted me, it tasted bitter but I forced myaelf to drink.
By the way, my 67 year old father was doing great. Disappointing him and ending his summit attempt was the toughest part of my decision.
Since I am writing this you know I am okay. I am at 8,000 ft again and feeling great after resting all day today. I hate we didn't make it but am happy to be safe and healthy. My thoughts are about all the maximum 7-8,000 ft mountains there are in Alaska where I never had to experience this again. It was a very scary experience and I've never felt that type of sickness before.
I am off to Yosemite tomorrow morning but have to be in Fresno by 6 for a high school reunion. I believe my dad is going to take me to the Tenaya Canyon "No hiking" sign I missed last year.
