Halfpipe skier Maddie Bowman has been on a roll lately. In 2013 and 2014, she earned gold medals in women's Ski SuperPipe at X Games Aspen, solidly blasting onto the top of the podium just after graduating from high school. She then followed that up by winning a little event called the Winter Olympics in Sochi, Russia, in February 2014.
