The two mountaineers who died on Mt Taranaki had little chance of surviving for two nights and a day in their shallow hole in the hard snow and freezing wind, says a leading local guide.
New Plymouth-based Ross Eden, who is also the editor of the New Zealand Alpine Club's guidebook for the mountain, told the Herald: "I wouldn't expect to survive if I was going to dig in and not get completely out of the wind."
Mr Eden was commenting on a report from the search and rescue team that Hiroki Ogawa and Nicole Sutton's "snow cave" was in fact only waist deep, leaving them exposed to the full force of the wind.
The MetService forecast for Saturday indicated cloudy periods would give way to drizzle at night, with a northwesterly rising to gales about the peak. The wind-chill was forecast to be -14C at 9pm.
Reports have suggested the climbers scraped out their shallow hole just below the crater area at about 2400m on the 2518m mountain - and that they were part of a larger group that arrived at the top of the East Ridge at about 7pm. The sun set at 7.54pm on Saturday.
