State license plates and tourism brochures boast that Utah ski areas receive the “greatest snow on Earth,” but is there really anything special about Utah's snow? Often it is argued in ski industry brochures that Utah's snow is the greatest because it is the “driest” (i.e., has a low density or water content), yet the mean water content of snow at Alta ski area, which is world renowned for powder skiing and provides the cornerstone for Utah's famous slogan, is not lower than observed, for example, at many Colorado and Wyoming ski resorts. We propose that Alta's reputation is not based solely on mean water content, but also abundant natural snowfall. Although it cannot be shown that Utah's snow is the “greatest on Earth,” the climatology at Alta and other nearby ski areas is consistent with a high frequency of deep-powder days.
