A man killed Sunday in a Sanpete County avalanche became the second victim to die over the weekend in a snowslide.

Four backcountry snowmobilers were riding near Huntington Reservoir when the slide buried Clint Conover, of Ferron, according to a Sanpete County Sheriff's Office news release.

The news release describes the group as "highly experienced" — they were trained in avalanche rescue and brought beacons, probes and shovels with them. The three other people found Conover, dug him out from under 6 feet to 8 feet of snow and began CPR, the release adds. They also called for help.

Search and rescue teams from Sanpete and Emery counties arrived with an ambulance from Fairview. The state park service also responded to the slide. However, Conover did not survive.

Conover, whose age was not immediately released, is survived by his wife and five children, according to the release.

Meanwhile, Ashleigh Cox, 21, a Brigham Young University student who was trapped in an avalanche in American Fork Canyon on Saturday while snowshoeing, was taken off life support Sunday afternoon.

Cox's family released a statement Monday afternoon, saying they appreciated "the love and concern" expressed by family, friends, acquaintances and fellow students. Cox planned to graduate this spring and wanted to further her education in social work, the family statement said.

Avalanche risk was deemed "high" throughout the mountains of northern and central Utah, and "extreme" in the Uintas, according to reports by the Utah Avalanche Center.
