Input: A British skier has died in the French Alps after he and two friends plunged hundreds of feet from a ridge while skiing off piste. 
  
 In a separate incident, a 13-year-old boy died when both he and his brother fell off a cliff after they got lost while skiing with their family. 
  
 The Briton, who has not been named, was with two friends in the resort of Oz-en-Oisans on Saturday when they decided to leave the marked slopes. Police said that all three men were in their 20s and were experienced skiers. 
  
 “They were following ski tracks but they got lost when the tracks came to an end,” a spokesman for the gendarme mountain rescue unit, based in nearby Grenoble, told the Telegraph. 
  
 “They saw a marked slope in the distance and were trying to get to that. But the area they had to go through was very unstable, made up of ridges and a mixture of snow and rocks,” he said. 
  
 All three ended up falling, but not at the same time. The man who died fell somewhere between 100 and 200 metres, said the officer. 
  
 “It looks like he died instantly. His body rolled down the ridge, bashing off rocks several times before it came to a halt,” said the spokesman. ||||| Get daily updates directly to your inbox + Subscribe Thank you for subscribing! Could not subscribe, try again later Invalid Email

Output:
Two separate ski vacations, two separate tragedies in the French Alps over the weekend. The first involved a boy said to be 12 or 13, who died after falling off a cliff at the Avoriaz ski resort, report the BBC and Mirror. Per LCI News, the boy and his 10-year-old brother had taken a ski lift up the mountain on Saturday, with their dad and 6-year-old sister by their side, but when they got to the top, the father opted to take the little girl down and let the boys descend on their own. It's not clear exactly what happened after that, but the boys seem to have gotten lost, taken off their skis, and wandered into the woods; at some point they both plunged 500 feet off a cliff hidden by trees. When they didn't show at the resort, the cops were alerted, and they were found at the bottom of the cliff early Sunday. The older boy was dead at the scene. His younger brother, whose fall was apparently softened by tree branches, survived with a broken pelvis and is being treated at a nearby hospital, with a local police official calling his survival a "miracle," per the BBC. The Telegraph reports on a separate incident at the Oz en Oisans resort, where on Saturday a British man died after he and two friends, all said to be in their 20s and good skiers, went off a marked ski run and got lost. A member of the mountain rescue unit says as the men tried to make their way back to the marked slope, they climbed a part of the mountain that was "very unstable, made up of ridges and a mixture of snow and rocks." All three fell at different points of their ascent, between 325 and 650 feet, and one man "died instantly." One of his friends walked away unhurt, while the other suffered just minor injuries.
