I’d carefully planned my altitude acclimation: one night with Markskor in Mammoth (around 8000’), a second night at a campground in Bishop Canyon (around 9500’), an easy first day in to Saddlerock Lake (about 10,500’), and by then I figured I would be good for Bishop Pass and what lay after.
Monday 9/1. I arrive in California, drive to Mammoth and have a great time with Markskor, who turns out to be one helluva cook (thanks again, Mark!), and I enjoy wandering around Mammoth a bit.
Tuesday 9/2. The highest campground near the Bishop Pass trailhead, called “Willow,” isn’t any great shakes, but it has the requisite flat spot, picnic table, and fire ring. A little dirty and no water (I have to filter from a nearby stream), but OK: good solid 6 on a scale of 1-10. I do a little day hiking; the first part of the Bishop Pass trail is a lot prettier than I remember it from 30-odd years ago, and I don’t seem to be having a lot of altitude problems.
Wednesday 9/3. I drive down to Bishop, where I meet Mary, finalize plans, and drive my rental Corolla to the Taboose Pass trailhead with Mary following, to set up our shuttle. I take the road slowly and gently and my rental car does just fine. Then back up to the Bishop Pass TH for a relatively late start around 4:00 PM. South Lake is hardly there at all. Wow, it is dry out here! Get to Saddlerock just as the sun is going down; dinner by headlamp. Thursday 9/4. The next morning I’m up early and ready to head up to the pass. No altitude problems at all going up. I stop briefly at the pass (you have to do that, right?

I hobble down to lake 10,742, where I’m supposed to rendezvous with Mary that evening, and I sit down and take stock. The cross-country adventure looks very doubtful at this point, and I even momentarily consider heading back up to the pass to abort the trip entirely, but of course I don’t have a car there anymore. Going down hurts, though descending into LeConte Canyon would be the obvious thing to do if it’s altitude that’s causing my problems. However, the symptoms aren’t at all like what I’m used to—no headache, for example. I dither for a long time and finally decide to make camp as planned but make bloody sure that Mary can find me. I find a good campsite well off the trail and across the stream and go down to the stream and wash, but I’m so exhausted and uncoordinated that I fall over in the stream and hit my back on a rock, hard: just what I need. Thoroughly discouraged, I hang around by the stream until Mary shows up around 5:00 PM, which buoys my spirits considerably. I notice that evening as I write in my journal that my handwriting looks like I’m about 105 years old. I feel it.
Friday 9/5. Next morning things look a bit better. I’m still very unsure of myself, and we start out a bit late, walking very gingerly. The place where the rock hit me hurts as I walk, but I make it across the stream OK, and we are further buoyed by the arrival of another friend, Rosie, who was planning to meet us at Deer Meadow that night but who is hiking incredibly fast and is ahead of schedule.
Unfortunately, the descent into LeConte Canyon is pure torture, at least at the beginning. I’m still uncoordinated so I have to pick my way down very carefully, my hips still hurt, and I still have to stop every 15 minutes to rest and readjust the pack. I really can’t trust myself to do the cross-country, and Mary—proving herself the best sport in the entire world—assures me that the work we’d planned on at her field site can be done on another trip, and I shouldn’t worry; we can do any of several simpler trips. I worry nonetheless. However, although I can barely allow myself the hope, as we descend into LeConte Canyon things seem very slowly to be getting better: the hips hurt less, the pack seems to be slipping less, and the rests come at longer intervals. By the time we reach the ranger station and have lunch, I’m optimistic but still not willing to risk the cross-country piece. We tentatively plan to switch our route to the much more gradual JMT route over Mather Pass, and also to break up the Taboose-Pass descent by camping in the middle. The level trail from the ranger station to the junction of Palisade Creek with the Middle Fork goes fast and easily, the way it’s supposed to. The gentle climb to Deer Meadow is also quick and trouble-free. The three of us find a very pleasant campsite just below Deer Meadow and enjoy ourselves. This is much more like it! Saturday 9/6. Rosie, poor working stiff, takes off to go back up over Bishop, and we make our way up the Golden Staircase and decide to camp at the last water before Mather. By the way, what, exactly do HST readers think (or know!) is the Golden Staircase? I’ve always thought it referred to the heavily engineered switchbacks between Deer Meadow and lower Palisade Lake, but an experienced hiker we met on those switchbacks said he’d always thought the term referred to the part of the trail that climbs above the lakes. Opinions?
Sunday 9/7. We go over Mather Pass, and I reminisce about the JMT through-hike I did with my son in 2005. Upper Basin has got to be one of the most spectacular places in the Sierra, but you know, there’s a lot of spectacular scenery to choose from in the Sierra… A few clouds have moved in (it has been absolutely crystal clear since the beginning of the trip, with warm days and near-freezing nights). It’s a high-traffic day on the JMT, and we meet perhaps twenty people in groups of various sizes, from oldsters like me to a northbound young guy in an orange Spandex suit who’s obviously trying to set some kind of record. We decide to take the unmaintained northern short-cut trail up to Taboose but can’t find exactly where it meets the JMT, so we head cross-country in the right general direction and eventually run across it; the trail gets more and more obvious as we get nearer and nearer the pass. Shortly before it joins the main trail, the shortcut trail becomes literally covered with obsidian flakes! Looks like somebody quite a long time ago was very busy here…
The view west from Taboose is incredible; “Quite an introduction to the Sierra, eh?” says Mary. But egad, after what a pass! Easy enough near the top, but after a while the descent gets pretty rough, and even in my [apparently] fully recovered state it takes a lot of care just to stay upright. Lots of lose rock, some extremely steep parts, and generally a very, very demanding trail. I try not to think too much about what it must be like to go up; one couple we met in Upper Basin told us they couldn’t believe how long and hard a climb it was, and going down I can appreciate that.
We stop just after sunset around the 10,000’ level and make camp. There are quite a few clouds that night, but we assume they’re just the usual evening Sierra clouds. Nope. Around midnight it begins to rain in earnest, so we execute the usual fire drill, hastily buttoning down and dragging packs into tents. Ah well, into every life…
Monday 9/8. We get up early and continue going down, down, down, getting to the rented Corolla in the early afternoon. It is obviously autumn: there are incredible quantities of berries of nearly every sort: elderberries by the ton, gooseberries, and even coffee berries. We wonder why the bears aren't eating them, then discover large quantities of seed-laden bear poop: they are eating them!

So, really an excellent trip in the end, though not without its challenges and discouraging moments. It does appear that the hip pain and coordination problems were altitude related, since the descent down Taboose caused none of the symptoms I experienced descending from Bishop, but it’s an entirely new kind of altitude problem for me. Has anyone else on the board experienced this kind of difficulty at altitude? Any other insights? Suggestions for future acclimation? I’m thinking maybe a week or so in Tuolumne Meadows before the next trip: oh, dear, what a sacrifice!
