The U.S. Coast Guard has suspended the search near Wales for two boaters missing since Sunday.
Alaska State Troopers identified the occupants of the rowboat as Wales residents Timothy Miligrock, 21, and Damian Soolook, 14.
An air, sea and land search was suspended at 2 a.m. Tuesday, according to Chief Petty Officer Joshua Ryan.
No sign of the boaters was ever found, Coast Guard officials said in a statement, despite a search that covered more than 2,300 square miles.
"Local villagers did find debris from the boat washed up on the shore," Ryan said.
Troopers said the duo reportedly left Wales, on the Seward Peninsula north of Nome, at about 2:30 a.m. Sunday. They were reported overdue about three hours later.
The Coast Guard sent C-130 search planes and MH-60 Jayhawk helicopters to the area starting Sunday, and they were joined by the University of Alaska Fairbanks research vessel Sikuliaq on Monday.
The search was "hampered by fog, wind, ice, and waves," troopers said, and the Coast Guard reported water temperatures in the area just under 40 degrees on Monday.
