This study examined patterns of snowfall intensity and 8 frequency in the Denver, Colorado area. Not surprisingly, the 8
frequency of snowfalls decreased as the intensity of snowfall 8
increased. Snowfall frequency was found to increase from 8
September to November, to remain relatively stable through 8
February, record a substantial increase in March, and decline 8
through May. Snowfalls less than three inches tended to peak in 8
January, while snowfalls from three through 11.9 inches tended to 8
peak in March, and snowfalls of 12 inches or more occurred most 8
frequently in December, with the second greatest number occurring 8
This research reviewed snowfall activity in Denver, Colorado 8
for the general 30-year period 1960-1990. Snowfall typically is 8
assessed by seasons, as opposed to calendar years (Improving 8
snow, 1994, pp. 7-8). Therefore, this review was based on data 8
for 30 snow seasons in Denver, which began with the 1961-1962 8
season and extend through the 1990-1991 season. The snow season 8
in Denver is considered to extend from September through May 8
(Scherer, 1992, p. 37). During the period analyzed, however, 8
traces of snow fell as early as July and August in 1990, and as 8
late as June in both 1974 and 1989 (Bair, 1993, p. 467). During 8
the snow seasons of 1990 and 1991, field studies in support
