Utah-native Johnny Collinson, all of 17 years old, just became the youngest individual to reach the Seven Summits. Backpacker's Daily Dirt blog has the story and reports that Collinson reached Vinson Mastiff, in Antarctica, earlier today. Collinson made it just in time. He began his mission to the Seven Summits in 365 days with a summit of Aconcagua on January 19, 2009. Congratulations Johnny.
