| That altitude is noticeable if you go straight from low altitude. When I walked to the summit of Mauna Kea from the visitor centre, the first 1200 meters were easy but the last 200 altitude meters were exhausting and it was hard to talk straight to people up there. Some years later I drove all the way up, and it was ok since it was effortless. Also, at similar altitude around lake Titicaca the altitude was no problem since I'd already been a week in Peru mostly above 3000 m.
In Peru I had planned to get to 6000 m, but I got a bad cold and had to cancel that.

need to be carefull when you going to such height. need to rest for a night every 1000 meters or so.
heard lot of stories of ppl who tried to climb that, felt not good up there and died somehow.
probably because of no rest and not giving the body time to adapt.
so be carefull when you do it! you probably allready know it!

| Yeah, that altitude is very noticeable, especially if reached quickly or with exertion. My first experience with being over 3000m was when flying from Santa Cruz (400m) to La Paz (4000m). The simple act of walking off the plane was enough to provoke gasps for breath. But driving up Mount Evans after spending several days in Denver was easy, and even hiking the rest of the way up to the summit wasn't bad at all. The altitude affected me more when I was merely climbing up ~2000m peaks like Vesper and Hardy, from being acclimated to sea level. Something about those last few hundred meters of gain is just brutal and an exercise of sheer willpower.
spacer, it's fascinating to me how the climate and ecology change so rapidly with altitude. Each 1000 meters of elevation gained is equivalent to moving between 1000 and 3000 kilometers poleward (varies by mountain range). In Colorado the treeline is very sharply evident at 3500m, and above that it's alpine tundra -- bare, windy and cold. Being in the mountains emphasizes just how thin our atmosphere really is.
And yes, it is also very important to be safe and cognizant of one's health at high altitude. Proper acclimatization is crucial, and so is awareness of serious issues like HAPE and HACE. If you feel like you can't catch your breath even when resting, that's not good, and neither is the feeling of being drunk or nauseous. altitude.org has great information.

| Watsisname, will asthma has any effect when you go higher?
i have asthma from age 0. i breath ok daily until there its strike.
i read that in colder places, there is more asthma, and i wonder if height is a factor too

| It can be, but depends on what typically triggers your asthma. Pollution and allergy-related may actually improve with elevation. But if cold or dry air are a problem, then altitude will generally make it worse. The best bet is if you're going to go up, don't do it too quickly. Allow yourself enough time to acclimate and see how you respond.

| Quote Watsisname ( ) Antza, I think these are your best flower/bees/notsobees shots yet. The level of detail is incredible!
Thanks!  And i agree, these are by far the best ones i've taken. I've learnt some neat tricks with my photo editing software to prevent ugly noise on high ISO images, so i can get a bigger focal point.
Quote Watsisname ( ) Some snapshots from another week visiting the high country in colorful Colorado.
I'm jealous. I would love to go hiking on a mountain someday, but so far haven't been able to because of my bad leg. Turns out i've had a spinal disc herniation for the last 4 years. Luckily i've now had it operated on and it's getting better. Hopefully i'll get to climb a mountain next summer.
Go to antza2.deviantart.com for cool photos!

| Yeah, thankfully this volcano doesn't tend to have very large or frequent explosive eruptions, and most of the activity is mudflows and lahars. Of course, any active volcano can have surprises.
The real scary one is Mt. Rainier near Seattle -- considered one of the most dangerous in the world. It's covered in glacial ice, and the underlying rock is very weak from hydrothermal alteration. So, if it goes, it will produce massive lahars that will engulf the neighboring river valleys. A lot of communities are built on top of old lahar deposits...
Finally the entire region is subject to infrequent but violent earthquakes from the Cascadia subduction zone, which runs all the way down the Pacific coast just off shore, producing quakes up to magnitude 8 and 9 with tsunamis that hit land just minutes later. It's a near certainty that it will go again (we can even measure the slowly building strain in the rocks)... it's just a matter of when. That's the risk of living in this beautiful area. Be aware and prepped for the disaster; hope it doesn't happen in your lifetime.

| yeah and we must remember yellowstone too! its very close to washington and if it erupt...2/3 of the u.s will be covered in ash.
i will always say it...ppl dont care about future disasters (earth pollution, earthquakes, volcanos, and more) until it slap them in thier faces. and that one of the problems of today leaders and governments.

I saw a map for this, and even where I live (North Texas) will have at least a good coating on everything and I'm sure the air won't be breathable for quite awhile...And I'm hundreds, nearly a thousand miles away!
Living among the stars, I find my way. I grow in strength through knowledge of the space I occupy, until I become the ruler of my own interstellar empire of sorts. Though The world was made for the day, I was made for the night, and thus, the universe itself is within my destiny.

| The scale of it is truly terrifying:
This basically ruins life in several states, and the climatic effects would be global. The economic impact is almost incalculable. It's so severe that there's really not much sense in trying to prepare for it on a personal level. You can't. The good thing is that these events are so rare that there's not much sense in worrying about it, either.
I think events like this also speak to how unfamiliar we are, as individuals, to what life goes through in the long-term. Earth's habitability is a gift and life is always at the mercy of whatever nature throws at it. Geologic time is best characterized as long periods of boredom, punctuated by short periods of sheer terror. There have been some pretty bad days. We're very lucky in that we have the intelligence and technology to prevent some disasters, like asteroid impacts.
On the subject of high altitude and oxygen, I thought the latest Smarter Every Day video was appropriate, educational, and a little bit scary:
He goes on an unpressurized flight which rapidly ascends to 25,000 feet (7600m), and under close supervision, removes his breathing mask to demonstrate the effects of hypoxia. I've heard, qualitatively, what this is like, but I've never seen it before. It's alarming. He gets down to about 60% blood oxygen level and becomes so impaired that he can't even comprehend the fact that he's about to die if he isn't put back on oxygen, let alone perform a simple task to save himself. You can see in his eyes that he's barely there; twitching and turning purple in the face, on the verge of passing out.
It's still amazing to me that the human body, given time, can adapt to and survive at that altitude, whereas sudden exposure to it would kill you in minutes.

| The look on his face is pretty disconcerting, you can see how badly he wanted to put that mask on but couldn't even move his hands properly.
