PROVO -- Authorities say a climber is in stable condition after a 40-foot drop in central Utah's Rock Canyon.
The Provo Police Department says 47-year-old Sidney Thomas and 19-year-old Keanon Thomas were injured while climbing after Sidney Thomas plummeted to the ground from 40 feet up a cliff.
Keanon Thomas was able to slow the descent by holding the rope and attempting to jam rappel device.
The two were taken to Utah Valley Regional medical center in stable condition. Authorities say Sidney Thomas suffered from shoulder pain and a visible head injury, while Keanon Thomas suffered from rope burns.
Officers say the rappelling device was functioning properly, but the rope may have been fed improperly through the device.
