The Upper Teklanika River in Denali National Park/NPS

Remains of a Georgia man who set out on a 28-day backcountry trek in Denali National Park a year ago have been discovered in the park's backcountry.

A park release said backcountry hikers came upon the remains at an abandoned campsite near the Teklanika River. They notified park rangers of the discovery on Tuesday.

Through limited human remains, personal effects, and communications with friends and family, rangers were able to identify the remains as those of Etienne Terrell, 22, from Atlanta. He had been issued a 28-day backcountry permit on July 3, 2015.

According to the park, Terrell had told family members that he was planning an extended wilderness trip in Alaska after his discharge from the military. He had not been reported as a missing person during the past year.

The cause of death is undetermined but will be further investigated by the Alaska State Medical Examiner.
