The warmest "average monthly temperature normally occurs during July and the coldest during January. Annual pre- cipitation averages nearly 11 inches, of which approximately half is normally received during May, June and July. The May-June period during 1974 was characterized by below normal precipitationi, while that received during the months of April and August was above normal. This was comparable to the trend exhibited during the same period for the two previous years (Table 1). The winter of 1974-75 was generally characterized by above normal precipitation and snow cover appeared to persist over longer periods than during the two previous winters. Temperatures during January 1975 were slightly above normal, while those during February averaged degrees below Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Dusek, Gary L; McCann, Steven A; Consolidation Coal Company; Montana.
