ConocoPhillips Alaska president killed in avalanche

(CNN) -- The president of ConocoPhillips Alaska was killed in an avalanche and another person in his snowmobiling party is missing, according to Alaska State Troopers.

The body of Jim Bowles was recovered near Spencer Glacier by rescue workers shortly after police received a 911 call at 12:30 p.m. Saturday, said troopers spokesperson Megan Peters.

"When we found him we attempted CPR but we could not revive him," she said.

Bowles, 57, was apparently out with friends snowmobiling in the Grandview wilderness area. Rescuers are trying to find Alan Gage, who is thought to have been buried in the avalanche, Peters said.

Bowles was the head of Alaska operations for the oil company, authorities said.

Alaska Gov. Sean Parnell issued a statement saying he and his wife Sandy "were deeply saddened today by news of the loss of Jim Bowles."

"Jim brought so much to our state: his love of the great outdoors, his leadership of ConocoPhillips Alaska, and his dedication to making Alaska a better place for all of us to call home," the statement read.

In a separate incident, miles from Spencer, another avalanche killed a skier Saturday afternoon. A woman who saw the accident called 911 while her husband was able to locate the skier's body. A dog accompanying the skier survived the avalanche, authorities said.

Between mid-February and mid-March warm temperatures cause layers of snow to become unstable.
