The largest reported snowflake on record measured 15 inches wide and 8 inches thick, according to a fun fact highlighted by Fox News.

This extraordinary snowflake was reportedly observed during a snowfall in Fort Keogh, Montana, in January 1887. The claim was made by a rancher named Matt Coleman, who described the snowflake as 'larger than a milk pan.' While the measurement is not officially verified by modern meteorological standards, it has been cited in various weather records and trivia lists.

The story was reported by Fox News as a lighthearted fun fact, drawing attention to the extreme sizes that snowflakes can theoretically reach under perfect atmospheric conditions.
