A 19-year-old South Dakota man who fell while climbing Montana's highest mountain peak earlier this month has died from his injuries.
Thomas Craig Pfeifle died at a hospital Monday.
Pfeifle had fallen 20 to 30 feet while climbing near the summit of the 12,800-foot Granite Peak on Aug. 8.
The Rapid City man had been rescued by helicopter and flown to a Billings hospital, where he was treated for a head injury. He was then transported to Harborview Medical Center in Seattle, where he died Monday.
A medical examiner says Pfeifle's official cause of death has not yet been determined.
Pfiefle is the son of South Dakota 7th Circuit Court judges Craig Pfeifle and Jane Wipf Pfeifle.
