Abstract
A snowfall of 87 inches in 27½ hours on April 14–15, 1921, was reported at Silver Lake, Colo. This snowfall, if correctly measured, exceeds others generally accepted as being record values for the United States. Consequently it is important to determine the reliability of the observation. There is no evidence to indicate that the measurement was any less reliable than that of other heavy snowfalls, and it appears that a snowfall of this magnitude is meterorologically possible. The Silver Lake snowfall is therefore acceptable as the highest known recorded value for the United States.
