The first unit arrived on scene at 10:37 a.m., established command and ascended the trail on foot.

It was reported that two male and two female hikers in their 20s were stuck in a precarious location and unable to safely descend.

All four hikers were safely airlifted, one at a time, to the nearby landing zone where medical care was refused.
