Snowflakes that fall at 2 to 4 mph can take about one hour before they reach the ground. Did you know that fresh snowfall absorbs sound, lowering ambient noise over a landscape? This is because the trapped air between snowflakes attenuates vibration. That’s why it gets so quiet when it snows. On January 28, 1887, did you know the world’s largest snowflake was recorded in the Guinness Book of Records measured 15 inches wide! The snowflake fell at Fort Keogh, Montana, USA.
