A 17-year-old from Minnesota died while climbing in Colorado on Sunday evening.
Carter Christensen of Maple Grove was climbing in Chautauqua Park near Boulder when he fell, apparently from the First Flatiron rock just before 6 p.m., the Boulder County Sheriff's Office said in a news release.
He posted a selfie from the First Flatiron shortly before he fell, the sheriff's office said. But investigators don't believe the selfie had anything to do with his death (it was posted about an hour before), the Daily Camera reports.
Christensen was climbing along without any ropes or gear, with the sheriff's office noting no one saw him fall. People in the area heard it, though, and went to help, but he was pronounced dead at the scene.
"Carter was a lover of the outdoors and an adventurous spirit and was experiencing joy in summiting the First Flatiron in Chautauqua Park," his family said in a statement.
His family's statement noted that he graduated from high school in June, and went to Colorado to be with friends and spend time in the outdoors "while he trained for his Navy SEAL enrollment."
The exact cause and manner of his death are still under investigation, the county coroner's office said.
