The curves for Lake Louise are shown in Figure 3. For Lake <br />Louise and all stations in the study area, the percentage frequencies <br />for September are lower than those for Apri 1. Thi s di fference is much <br />greater for stations in the Alberta foothills than for British Columbia <br />stations. Low September snowfall is due to higher temperatures in that <br />month. In April, snowfall is infrequent at stations west of the <br />Continental Divide, whereas, at most stations east of the Divide, <br />snowfalls of a given size are just as likely to occur during mid-winter. <br />
