This morning's Oregonian had a theory that officials had about what happened (keep in mind this is just a theory) based on what they saw.
"Thompson, 32, also a sheriff's deputy, served as operations director, shuttling between the trailer and a room next to the first-aid station in Wy'east. There, several people sat around a table and hashed out theories about what became of the climbers.
Their biggest clue arrived Monday when a medical examiner declared that Gullberg had succumbed to hypothermia. Until that point, the working theory was that Gullberg had died in a traumatic fall.
But it was the families of the three climbers who provided crucial information to put some pieces together, Thompson said.
Family members told rescuers that Gullberg was the strongest among three experienced climbers and that Vietti had wilderness medicine training.
It was only one of many theories, but at a news conference Tuesday, Thompson offered the leading scenario:
There'd been a serious climbing accident high on the headwall of Reid Glacier in which Nolan lost a mitten. Gullberg gave her his gloves and took the remaining mitten for his descent.
Thompson expanded on the scenario Wednesday, saying perhaps Vietti, with his medical background, stayed behind with Nolan. Emphasizing again that it was a theory, Thompson suggested that Gullberg's path to hypothermia could have begun with the strenuous task of digging a snow cave.
In his deteriorating condition on descent, rescuers deduced that Gullberg shed Nolan's green Outdoor Research mitten and his light-gray Black Diamond climbing helmet in the delirium of hypothermia."
