Cox, 21, was snowshoeing with several other people when the avalanche happened.
Emergency responders dug her out, but she was buried for about 40 minutes and was not breathing when they got to her.
Her heart began beating again a little later and she was treated at the Utah Valley Regional Medical Center, reported the Salt Lake Tribune.
However, Cox died on Sunday evening after being taken off life support, reported KSL.
The Utah Avalanche Center has issued a red level advisory, warning people of high avalanche risk.
