Brien had entered the narrow area of the couloir above the rappels when the avalanche occurred, the park service said.
“The avalanche was up to two feet deep and fractured fifty to one hundred feet above Brien, sweeping him over the rappel and downslope for approximately one thousand feet,” it said.
Others with the group called 911 and alerted friends who were also skiing.
“Both parties made their way to Brien and found him partially buried,” the release said. “They removed him from the debris and initiated CPR.”
The victim suffered “significant trauma and was determined deceased at the scene.”
