PROVO — Search teams were looking Wednesday night for a lost hiker stranded on Y Mountain.

The man called 911 with his cell phone at 8:17 p.m. and informed police dispatchers that he had left the Brigham Young University campus earlier in the day and headed east up the mountain.

When he called, he said he could see the city lights but could not find a way back. He had no light source with him.

Searchers drove trucks into the general area and began flashing lights and using a noisemaking device to guide the man, but those efforts were unsuccessful.

A helicopter from Life Flight joined the search a short while later with night-vision equipment, and the man stayed on the line to tell dispatchers if he heard or saw the helicopter near him. Dispatchers asked him to hold his cell phone up to give the helicopter crew some help in seeing him.

As of press time, the man had not been found, but crews were narrowing in on his location.
