BIG COTTONWOOD CANYON — An 18-year-old boy had to be rescued from Mary's Lake Monday when he and some hiking companions decided to cool off in the lake.

The teen became distressed and began to slip beneath the water before friends managed to get him to a large rock and bystanders rendered aid. He was taken by medical helicopter to a waiting ambulance, and once he had recovered, the teen was released without being admitted to a hospital.
