Missoula police say Michel Colville died Sunday night at St. Patrick Hospital. Her husband, Fred Allendorf, remains hospitalized in serious condition.
He was buried for about two hours before rescuers found him Friday night in an air pocket created by a fallen chimney in their house at the base of Mount Jumbo.
Eight-year-old Phoenix Scoles-Coburn was buried in the snow for about an hour. He was released from the hospital Sunday.
Phoenix's 10-year-old sister, Coral, also was outside playing when the slide hit at 4 p.m. Friday, but she was able to dig herself out of the snow.
