PROVO — A Brigham Young University student spent almost 12 hours on Y Mountain before being rescued by Provo police late Wednesday night.

John Spelta, 19, planned to hike up the mountain and left his apartment around 11:15 a.m., said Provo Police Capt. Rick Healey.

Spelta apparently took a wrong turn and ended up in a steep area of the mountain. When he tried to come down, he hit another steep area and got wet from the snow, Healey said.

The man called 911 on his cell phone at 8:17 p.m. and told the police he could see the city lights but he couldn't find his way down.

Search trucks and a Life Flight helicopter were dispatched and used night-vision equipment to find the man.

When Provo fire and police crews found the man around 11:30 p.m., they got him into some warm clothes, built a fire and gave him some food before bringing him down on ATVs they had taken to the top of the giant stone Y on the mountain, Healey said.

Healey said Spelta was cold and dehydrated but unharmed and spent the night in Sandy with his family.
