There were 45.7 inches of snow on the ground in Denver on December 5, 1913.
For four days, a massive blizzard hit Colorado. It remains the largest snowstorm recorded in Denver's history.
According to the Denver Public Library, the snow began on December 1 and continued through December 5 leaving the city blanketed under more than 3.5 feet of snow.
Some mountain communities saw even more astounding numbers: Georgetown recorded 86 inches and Estes Park had 53 inches of snow, according to the website Weather5280.
More than 100 years later, we still have not come close to breaking that record.
The second biggest blizzard was in 2003, when 31.8 inches of snow fell in Denver.
