| Comments | Southern Alberta, April 17-20 and April 27-29, 1967. A series of intense snowstorms dropped a record 175 cm of snow on southern Alberta. The deep snow blocked roads, closed schools and cut off power. Army units were dispatched to assist in the snow clearing, while food, fuel and cattle feed were airlifted into the province. Thousands of cattle, unable to forage for food in the deep snow, perished on the open range. |
