O.k. here’s my story: I summitted Mt. Whitney (14.5K) a looooong time ago (like 35 yrs?) with three other women. We were all reasonably fit, but Whitney is not a technical “climb.” It’s basically a hike, but at a pretty high altitude. We decided to take at least three days: two to reach Lake Consultation, one to summit, and return to the trailhead the following morning. Well, it didn’t help me acclimatize. I got a bad headache when we set up camp at the lake (about 11K). I rested that night and felt better the next morning.
From that point, you take about 100 switchbacks to Muir Pass where you cross over to the western side of the mountain, and it’s a not too long hike to the summit. Well, by the time, we got to Muir Pass, I was feeling really bad again and was vomitting. The woman who’d organized our hike was the fittest among us. She said she’d go on to the summit. The other two stayed with me. When L returned from the summit, the plan was they’d go on to summit, and L would help me back to our camp.
Heh, I wasn’t going to get that far not summit! So, I kept walking and stopping and walking and stopping. Literally about every 10 yards, I’d stop. We finally got to just below the summit (there’s a kind of “knob” on top) and just coming down was L! So, she turned around and all four of us went up (I was literally crawling) and had our summit time (and signed into the guest book – dammit! I’d barfed all over that mountain, I’m gonna sign in!). We all went down together, and I just crashed, after eating a little dinner. And it was so weird to head back to the Portal the next morning. It was like with every single step, I felt better. By the time we got to the Portal store I felt completely normal. I bought a shower, a beer, and a bag of Cheetos. Ambrosia.
Another difference with Whitney is that it’s so popular you have to reserve a spot months in advance or take a chance on spots being available when you get there. So, there’s a ton of people. Everywhere. There was a big group of boy scouts who summited the same day we did (we walked through their camp heading for the switchbacks while the leaders yelled at the boys feeding the marmots oatmeal from their mess kits), and one of the leaders sat down with me on the western side to make sure I wasn’t too bad. No one left me on my own.
tl;dr? But such a different situation. And, yes, altitude can make you sick. And it can make you dangerously disoriented. I wasn’t that bad, but it can be life threatening, for sure.
Oh, the other two women were going home to the Valley, and Land I were on the Westside, so L and I drove back to L.A. together and stopped at a coffee shop in Lone Pine and ate two giant blue cheese burgers. We earned it!
