Rescue crews assisted two hikers who were hit by rocks Monday while climbing to the block Y above Provo.

Police officials said an 18-year-old man, a 17-year-old boy, and two 17-year-old girls decided to climb to the Y on the mountain above Provo at about 11 p.m.

Authorities say the group made it to the Y and then continued to climb above the block letter to an area known as Eagle's Pass. The 18-year-old and one of the girls decided to climb down at that point, but the other two continued to climb.

They later became stranded, police say, and were struck by rocks rolling down the mountain. The boy called 911 just before 4 a.m., telling dispatchers that they were "bleeding profusely" and they both had concussions.

Provo Mountain Rescue and Life Flight located the stranded hikers using infra-red gear, police say, and crews were able to climb to the teenagers and help them down the mountain. They were treated for their injuries at the bottom of the mountain.
