(CNN) -- An 11-year-old girl was killed and her mother injured when a huge chunk of ice struck them near a cave attraction in Washington state.
The two were on a family outing Saturday near the Big Four ice caves in Mount Baker-Snoqualmie National Forest, authorities said.
The family spoke to CNN affiliate KOMO on the condition their last name not be used. The girl's name was Grace. She, her parents and younger brother, William, were on an ice field next to the caves when they heard a "pop".
Grace's mother, Tamami, told KOMO: "I turned my head to the right, then I see the big chunk of ice falling down. I tried to snatch my daughter but I couldn't," she said.
Witnesses said Grace was hit by a chunk of ice about half the size of an SUV. "I tumbled down and I lifted her up and asked her, 'Grace, are you OK?'" her mother told KOMO. "And she look up at me and (was) already oh so pale".
Her parents and others performed CPR for more than an hour, but Grace died at the scene, KOMO reported.
Her mother was injured in the leg, but she was not hospitalized.
