With ski season is just around the corner, we’re going to look at the tension between the ski industry and environmentalists. It’s the subject of the new book “Colorado Powder Keg,” by western historian Michael Childers. At the heart of his book is the fact that skiing in Colorado brought with it tremendous growth. Starting in the 60’s, Vail went from ranchland to world-renowned resort in the span of a decade. And growth continues today. Some embrace it. Others loathe it. Concerns over growth famously led Colorado voters to reject the ‘76 Winter Olympics after Denver had been named host city. That's just one chapter in Childers’ new book. He speaks with Ryan Warner.
