Two people _ a snowmobiler and a snowboarder _ were killed in separate avalanches in central Utah, authorities said. Also Saturday, about 24 kilometers (15 miles) away in Ephraim Canyon, a snowboarder buried in an avalanche was rescued by a friend, but Garett Louk Gordon later died, authorities said. He was 26. Temperatures Saturday climbed above 4 Celsius (40 Fahrenheit) after several days of snow storms, creating dangerous avalanche conditions. At least five people have been killed in Utah avalanches this winter.
