Authorities believe 16-year-old Jake Revere struck a tree during an outing with his family.
Lehigh County Coroner Scott Grim says a weekend autopsy shows he suffered trauma to the upper body.
Officials say Revere was found unresponsive Friday on a trail at the resort in Tannersville, Monroe County.
He lived in Buckingham and was a student at Central Bucks East High School.
