A 63-year-old woman who was nearly crushed to death by a boulder that crashed into her house in southern Utah is grateful be alive.

Wanda Denhalter was sleeping alone Saturday at 3 a.m. in the middle of a king-size bed when a 12-by-9-foot boulder came barreling through the wall of her house in St. George, Utah. Her husband, 62-year-old Scot Denhalter, says the boulder broke off from a cliff above the house and came bounding into the house.

Scot Denhalter was sleeping at his son's house to make room for visitors that never arrived. He says Wanda Denhalter would have been killed if he had been in his usual spot in the bed.

She is in great pain after suffering a broken jaw, sternum and major gash in her leg.
