Since then he has put his time in learning the tricks and trades of the outdoor world. In summer, Jordan spends his as much time as possible in the high alpine with either his rock shoes or hiking boots on. In winter, it is hard to find a day when his feet aren't crammed into ski boots for some adventure or another. In 2009 Jordan became the youngest and the 5th person to ski from the summit of all 54 of Colorado's 14,000 foot peaks.
