At approximately 9:30PM on September 21st, the Palm Springs Mounted Police Search and Rescue responded to a 911 dispatch of three hikers that were on the Skyline trail at approximately 4,600 feet and having a difficult time returning to the trailhead. PSMP-SAR had members hike up Skyline to meet the hikers. Once members of PSMP-SAR were on scene with the hikers at Box #1 (2,500 feet) they provided medical aid to the hikers who were suffering from fatigue as the hikers had hiked to the tram only to realize that they had to turn around because they had been given false information that the tram was open when it was actually closed for maintenance. PSMP-SAR members hiked the fatigued hikers off the mountain. At approximately 5:30 AM all personnel and hikers were off the mountain.
