Eac hmonthly mean represents a mean of no less than two years occurring within the period of 1965 to 1971 . The data does not provide an accurate picture of the longtermweather and the values for Lake Louise do not agree with Table 1 . The data is presented to show relative differences (readings taken at the same dates) i ntemperature and precipitation within Yoho National Park .2 These values are calculated from data in the Monthly Record of Meteorological Observations in Canada (Environment Canada Staff) .
