Re: Mt Dana

Anyone been up Mt Dana recently? Was supposed to climb it with a few friends a couple of weeks ago on the way back from Mt Russell, but weather was bad. Thought I'd make a quick trip down there tomorrow before the weather gets bad again; which is what's forecast for the week. Wondering if there's any snow up there. Just thinking about doing the class 2 route.

Thanks

Last I heard there should still be some some on Mt. Dana from the storm that came through recently. And there will be more snow coming this week:

Went up yesterday and climbed Mt Dana. There is some snow up there. Not much, but what there is, seems to be sitting right on parts of the trail, making for slippery footing in some spots, and in others, obscuring the the thin trail altogether. A good exercise in route finding. It was a beautiful day though, and the views up there are well worth the climb, though coming from SF (sea level) the same morning, made it a bit of an adventure. The view of Mono Lake is awesome, as is the Lyell Glacier and all the rest of the Yosemite wilderness you can see from up there.

It was about 1 degree C in the parking lot by the east entrance at 9am (drove from SF). It got windier as the day wore on, and a couple of guys on top who were testing stoves for a backpacking company, said there was likely to be quite a bit of new snow over the course of this week. I got the impression from a ranger that if they get a good dumping of snow they'll probably close 120. Some friends of mine have been wanting to climb Mt Dana, but by the time they could went to this one's birthday or that one's anniversary, the earliest was next week. Fortunately, I checked the weather, and said it's now, or wait till next year. A long drive up, and a long drive back, but much better than going all the way to Lone Pine for Whitney or Russell.

Funny, for a mountain 13,000ft+, it gets climbed as an up and back (churn and burn) quite often. It is the same way that I did it in August. We also did it in June when there was plenty enough snow to glissade. It's a great mountain with or without snow (it is a much quicker return when there is snow, I have to say -- twice as fast when you don't have to slog down the face in scree)

It's a 3 mile hike. Why wouldn't it get a lot of hikers?

It looks horrific.

It's really not too bad a climb, if you are ready for the elevation. I could not start at sea level and go up in one day. I assume snow would make it tougher.

Bill-e-g and I did it a few years ago. Drove up from San Jose (elevation about 1') jumped out of the car, hit the peak, and drove back to SJ. We don't look at all happy in the pictures.
It is an easy hike except for the elevation.

I did it with snow. In some ways the snow made it easier. But by afternoon the snow was getting soft and that didn't help.

To a zeroth-order approximation, one experiences a 3% drop in air pressure (also, air density and oxygen intake per breath) for every 1k (ft) elevation change up to15k:
http://www.engineeringtoolbox.com/air-altitude-pressure-d_462.html
Therefore, at 10k, one is inhaling only about 70% as much oxygen per ‘standard breath’ (actually, per unit volume) as one does at sea level.

Of course, this is not the whole story as one still needs to transfer the oxygen into the blood stream. Below are some useful discussions of altitude sickness and the physiological response of the body to high altitudes:

Would crampons be worth the weight on the climb up?

Tell me about glissading-- do you use an ice axe? should one get instruction on this technique? do you use your pack as pad or something else?
I have done something similar years ago coming down Mt. Shasta but it seems that we sort of "skied" down in a crouch, which in retrospect seems like a good way to damage an ankle.

Dana looks like a great "training hike" for a beginning mountain walker. Probably good training for Whitney.
I have searched this forum for "Dana" back 6 years and surprised to find only a few discusions. Did I miss some?

Of course, SummitPost has some info:

We were lucky that the snow was just perfect when we went up 21 June, I believe -- soft enough to plant a step, firm enough to not post hole, so no crampons needed. EEEK has gone up earlier and I believe that he had an ice axe, but did not need crampons(?) To generalize, one would normally use an ice axe (with prior instruction) when glissasding, but my experience was that Dana has a gentle enough slope AND the snow was soft enough that there was never a threat of reaching terminal velocity on our trip. For Shasta, I used the crouch method, because the area I was climbing was steep enough to keep the momentum going, but for Dana, I brought glissade pants and just slid down as if riding on a tobbagan or snow disk (sooo much fun!)

brought glissade pants

Are these substantially different from insulated ski shells??? A whole new outfit to glissage?

No, no -- they are OLD shell pants that drop down the food chain to "glissade" status, meaning that I don't care if they get ruined.

Looks like there are actually "new" glissade pants marketed at REI and other sources.

The stats are a bit daunting: 3,000ft in three miles -- a thousand feet per mile, same as the Mountaineer's Route.

It is not an "official" trail, so it is almost never mentioned in the guide books; people just don't know that it exists. (I had it all to myself after about the first mile, when the others turned back)
