OK...understood...again MINDSET. Let's say we take a very optimistic view and assume 3MPH..that's 2 1/2 hrs, including any rest periods. Let's assume they're accurate in the calculation in completing the hike in that time frame. Would they then have been properly prepared given what we know?
They would have been woefully inadequately prepared, in exactly the same ways as the 2 mph frame. It wouldn't have been quite as hot, though, during the hike. But it would have been much more strenuous on the uphill.
We actually don't know how fast they went. They could have been hiking at 3 mph and headed up the SLT at 1/2 mile per hour, with gusto and no water, thinking they'd soon get to the car.
They may even have decided they wouldn't need any rest.
I'm guessing the sheriff didn't have the temperature figures for the bottom of the canyon, but only those where there was a temperature gauge. The bottom of the canyon would have been worse than the top, just not as strenuous as SLT.
This whole catastrophe blows my mind. The only thing I can imagine is that they planned in the realm of theoretical, but didn't understand that nature doesn't operate in the realm of theoretical: nature "is what it is". Staying safe in the natural universe requires experience, knowledge, information, and common sense. The tech world lives and dies from theoretical; all the money is in what you can dream up. On a hike, nature is making the rules, not you. That's the opposite of tech.
I'm saying this, because I'm trying to understand how the whole series of catastrophic decisions came about. This trip had no chance of being successful before they even set out. It was theoretically possible to them. It doesn't seem to have been even theoretically possible to any other posters here. Maybe living and breathing "high tech world" sealed their fate.
IMO there will likely be some argument about this, but yoga (EC's
metier) is also highly practiced in "high tech". Same with mindfulness. Whenever I've gone to yoga, it's seemed to have a dangerously high potential for competitiveness (injury, too), e.g. in the degree of stretch. It also involves "mastery", e.g. of the body and/or a sequence of movements. I can see yoga being turned into just another ruthless, ambitious, competitive quest that I see in the high tech world. In that context, it would not be about "being present" in an integrative way, but rather about being the best at a task and mastering a soul-full art. In other words, I don't think SFO tech and yoga practice are at all incompatible, but reinforcing, crazy as this may seem to some yoga practitioners. Perhaps this mindset was part of the problem, too.
