Thanks for this interesting tidbit of information Denis. Math was never my forte in school so I wonder if this example is just coincidence that there exists a 2 to 1 ratio of percent to degrees or can this comparison be used in all cases? ie: 70 percent slope = 35 degrees, 60 percent = 30, 50 percent = 25 etc. Thanks Jim - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - SkiVt-L is brought to you by the University of Vermont.
