Today's Weather Trivia

28 July

2002: Over 30 years, Norman Bethune Sanson hiked 1,000 times up Sulphur Mountain to check the weather station. Every other week, Sanson, the Banff weatherman and Park Museum curator from 1896 to 1931, made detailed records of the area's weather patterns and its flora and fauna. On this day, a Parks Canada guide took a group of hikers up the mountain to honour Sanson on Parks Day.
