The snow didn't stop after the 24-hour record was set. The snowfall total grew to 221 cm in 27.5 hours and 241 cm in 32.5 hours.

The snow in Silver Lake eventually stopped, leaving the record for most snow in two days up for grabs. From Dec. 29-30, 1955, Thompson Pass, Alaska, nabbed that record with just over 10 feet of snow.

In 1997, Montague, N.Y., reported 195 cm of snow, trying to beat the Silver Lake record. National Oceanic and Atmospheric Administration (NOAA) reviewed the submission and determined that proper guidelines weren't followed to measure the snow in Montague and, therefore, the 1921 snowfall record persists.

Snow records work both ways. Florida and Hawaii are the only two states that haven't exceeded a foot of snow within 24 hours. The most snow Florida has recorded over 24 hours is 10 cm, which occurred in Milton in early March 1954.
