Officials have released a dramatic video showing the rescue of injured skiers near Steven’s Pass in Washington state last week, and some wearable technology is being credited with helping guide rescuers to their location, according to a Fox Weather report.

According to information provided by the King County Sheriff’s Office Air Support Unit, an Apple Watch SOS alert from a backcountry skier was received by the Chelan County Sheriff’s Office on Wednesday.

The only information provided to rescuers was that the unidentified skier had fallen about 1,000 feet and sustained a leg injury, and the King County Sheriff’s Air Support Unit was able to respond just after sunset.

The video shows the rescue helicopter approaching the area, and the skier’s friend can be seen waving in a desperate attempt to get the rescuers’ attention.

"We have a second patient with a knee injury that’s still down there," a rescuer could be heard saying.

The skier could not walk, so it was decided to hoist all three skiers into the helicopter and bring them down the mountain to safety.
