With the approach of Labor Day, the first turns of the ski season are probably only seven or eight weeks away. To whet your appetite, we offer the trailer from the 70th Warren Miller ski film, which will be touring Colorado in November at the usual theaters including the Paramount in downtown Denver. This year’s film, “Timeless,” includes segments shot in Wyoming, France, Switzerland, Austria and two Colorado locations, Eldora and Silverton Mountain. The Eldora segment looks at the local characters who help make that modest mountain west of Boulder unique.
