On February 3, 1947, the record-low temperature for continental North America was recorded in Snag: -63 °C . That same winter, two previous records had already been set: one on December 13 in Mayo, Yukon and another at Snag the day before. Staff at the station made note of various phenomena, particularly sound such as voices being heard clearly miles from their source. There was a clear sky (except for some ice fog), and little wind.
