The bitter-cold waters of the Great Salt Lake likely killed four members of a California family after they had survived the initial crash landing of their airplane last week, says Box Elder County Sheriff Bob Limb.

"You just wouldn't be able to last very long in that water, it's so cold," Limb said Tuesday.The sheriff said that medical examiners determined all four men drowned after the pilot belly-landed the craft in the lake's remote northwestern arm. The plane sank in about 30 feet of water.

The victims had taken off Feb. 13 from Ogden-Hinckley Airport on a return flight to Chico, Calif. They had been in Utah attending the funeral of a relative. The single-engine plane disappeared from radar after the pilot radioed he was having icing and engine problems.

The bodies were recovered about two hours after the last radio contact with pilot.
