Don't forget guys, he was hiking at 8300 feet. Water doesn't boil in 6 minutes that high up (point 1), if he only had 1 cannister for his MSR he might have been trying to conserve or been out (point 2), and do cannister stoves even work well that high up (point 3)? Every time I camp I have a MSR white gas type.
The boiling point temperature for water gets lower to reach a rolling boil at altitude so actually uses less heat energy to bring to the boil. A 30 second rolling boil at altitude isn't going to get the water any hotter unless a pressure cooker was used to raise the water temperature (@ 8,500ft the boiling temperature of water is around 91C). Water actually boils more quickly at altitude than at sea level but with a lower temperature. Killing the nasties in the water is a function of the time and the temperature. So if 1.5 litres of water can be brought to the boil in 6 minutes the same amount of water can be brought to the boil in around 5 min 30 sec. So perhaps in this story the unfortunate hiker may have concluded that the water needed to be boiled for a much, much longer time, but all that is required is a rolling boil in addition to only the extra time you have saved due to bring the water to the boil due to the altitude.
Altitude is not really a problem for gas cartridge stoves, in fact the lower air pressure allows for better cold temperature usage. Gas cartridge stoves are effected by cold sub zero temperatures due to the boiling or vaporisation temperature of the butane content. But with using isobutane/propane cartridges and a chemical heater/neoprene insulation bag, operating temperatures down to -20C can be achieved.
Stoves such as Primus Himalaya Omnifuel can use gas cartridges again down to very cold sub zero temperatures by inverting the gas cartridge and using the butane/propane as a liquid fuel source.
I don't think in this case there was any issue in using the MSR Reactor stove (great stove BTW) even at altitude. No doubt the it would have otherwise been flagged up as yet another equipment failure.
Yeah, he made mistakes. But he made a plan, stuck with it, modified it when needed, and survived. Sure, he made some probably less-than-ideal decisions, but he did the big things right:
water
shelter
signal
fire
food
I think from the article that this hiker has access to water; to shelter; to fire; to food and had a good idea that someone was looking for him and that he was 18 miles from safety. I don't think any inclement weather played a part in this story.
What exactly was he surviving against? Was it his own inability to use a map and compass and the mental bridge of realizing he had a long walk home?
Could it have been that due to the embarrassment that if he wasn't somehow a victim of the wilderness then walking out of his predicament whilst SAR are carrying out the full scale search would have made himself look a little silly in front of the SAR professionals, his friends, family and work colleagues? Sometimes telling folks when your meant to be back from the wilderness trek can backfire.
