Each year, a multitude of publications produce "best of" lists telling skiers and snowboarders where they should ski. Heck, Curbed Ski even has our own round up of the best ski towns to visit in 2015-2016. But one of the most popular of these annual lists is Christopher Steiner's top 10 list on Forbes. Using a complicated algorithm that assigns each ski resort a Pure Awesomeness Factor (PAF), each year Steiner crunches data on 30 different categories for 220 North American ski areas. The results? A well-researched perspective on where to ski.
