The Big Idea: BlueDot

One morning in July 2006, Michael Garton was making a solo ascent up Norway’s notorious Troll Wall. At 3,300 feet, it’s the tallest vertical rock face in Europe. The U.K.-born Garton, then 24 years old, had scaled many of the continent’s major peaks and was ready for a bigger challenge. He calculated a week of 18-hour days would be enough to get him to the top. This would be the climb of his life.
