A 15-year-old girl, thrown from an ATV driven by her younger sister, was air-lifted to Primary Children's Medical Center in Salt Lake City on Sunday after it appeared the handlebars had punctured her abdomen, Weber County Sheriff's Sgt. Ryon Hadley said.
The accident occurred in the Dry Bread Pond area of Monte Cristo at approximately Mile Marker 40 on Highway 39.
Weber County paramedics treated Kayla Stevens, of West Haven, at the scene before sending her to Primary Children's.
She was in fair condition Sunday night, hospital spokeswoman Bonnie Midget said.
The 13-year-old sister, whose name was not available, also was thrown from the ATV but was not harmed by the rolling vehicle.
"The 13-year old, after they crashed, didn't really remember much of what happened," said Hadley. "They were on an incline and going downhill, that we know, and somehow lost control, and it threw them both off."
The two girls were alone at the time of the accident, which took place around 5 p.m., but were near the campsite where the rest of their family was staying.
