Abstract	A seventy-year record has been compiled of the number and mass of avalanches and the length of railway covered by avalanches at the Canadian Pacific Railway at Rogers Pass, British Columbia. The data showed only weak periodicities of avalanche activity. Several frequency distributions were analyzed for fit of the data, and the Gumbel method found appropriate for short return periods, but the sample period was too short to make conclusions with respect to probable maximum events. The weather before and during intense periods of avalanche activity was investigated and two different circulation patterns responsible for frequent avalanches were defined.
