A woman was killed and four other people critically injured during an explosion on house boat on southern Utah's Lake Powell late Wednesday night.

San Juan Sheriff Rick Eldredge said the blast occurred about 10 p.m. in Crystal Springs Canyon portion of the Glen Canyon National Recreation Area, which straddles the Utah-Arizona border.

The explosion came as the victims were attempting to start the house boat's generator.

Four other people suffered critical injuries — including burns, broken bones, and facial injuries — and were transported by air to Salt Lake City and Grand Junction, Colo., according to a joint news release from the San Juan County Sheriff's Office and the National Park Service. Three helicopters and an airplane were provided by Classic Aviation, officials said.

A male juvenile who suffered minor injuries was transported by vessel to the Bullfrog Clinic for treatment and was released.
