Utah County Sheriff's Sgt. Spencer Cannon confirmed that Ashleigh Nicole Cox, 21, was taken off life support at about 4 p.m. on Sunday.
21-year-old Ashleigh Nicole Cox was buried in the snow and submerged in a nearby stream for close to 40 minutes, according to Utah County Sheriff's Sgt. Spencer Cannon. It took rescuers about 20 minutes to locate her after the slide and another 20 minutes to get her out of the snow. Cox is from Colorado Springs, Colo. and was studying at BYU.
Cox was snowshoeing with a group in the Tibble Fork area of American Fork Canyon on Saturday afternoon when she was carried away by a slide. The avalanche carried Cox to a nearby stream and she was submerged under 2 to 3 feet of water, according to Cannon. When she was finally rescued, Cox showed no signs of life and was rushed to American Fork Hospital. Later, she was transported to Utah Valley Regional Medical Center in Provo.
The mountain areas near Provo had been under high avalanche danger on Saturday, and there had been reports of spontaneous avalanches in the American Fork Canyon area, according to Cannon. Cox did not have an avalanche beacon, he added.
Cox was from Colorado Springs, Colo.
