By the time you ‘hit’ any of these landmarks, you would have fallen headfirst over a half dozen ledges and frozen waterfalls that you would not have been able to discern in the 75mph winds blowing thick frozen fog into your face, caking up your goggles and disorienting you. Those were the whiteout conditions that were present on Feb 14.
Not my idea of a good escape route--definitely a last resort only.
And since when has a last resort by definition become a bad choice? By definition, the last resort is the least desirable of all possible viable options, after rejecting or trying all those other options. “A final expedient or recourse to achieve some end or settle a difficulty.” It is not by definition a wrong decision. It is the last viable option remaining. Consider their other options (in no particular order):
Continuing down the Crawford Path – Not Good
Going back up Mt Washington – Not Good
Ammo Trail – according to Lt Doug Gralenski of NHF&G, “but they were looking for ways to get out and searched around for some trailheads with no success." Already tried and rejected.
Stay put – they tried that for three days and they exhausted their fuel. So without water they would get weaker and more dehydrated and thus, more prone to hypothermia. They had no way to know how long the storm would last. For three nights this option did not work. It was time to move on.
Dry River Valley – not optimum but under the circumstances, viable, safe and necessary.
If the weather conditions are too bad to follow a compass bearing into the wind, best to stay put, even without food and fuel, especially if you have bivi sacks and sleeping bags.
Which is exactly what the couple did for three nights (Wed-Thu-Fri). At that point they were out of fuel, low on food or depleted (they were carrying 3 to 4 days of food based upon their friend’s comments), probably getting dehydrated (leading to hypothermia) and needed to get moving. Your own words imply that there are weather conditions where you could not follow a compass bearing yet you insist that they should have tried to do so anyway. After 3 days of following this advice, they found a better solution.
Dropping into Dry River from the southern Presi's is like dropping into Lincoln Brook from Franconia Ridge, that is too long a way out.
Long, true, but it’s probably a hell of a lot safer than dropping into Walker Ravine or wandering off the northwest side of Mt Lafayette under like circumstances.
Here are a couple quotes from Fish and Game Lt. Doug Gralenski to reconsider:
"If we didn't do anything, they would have come out this evening on their own,"
"They did everything right," he said. "They just ran into bad weather."
