- More snow falls each year in southern Canada and the northern US than at the North Pole.
- Large snowflakes can measure up to 2" across and contain hundreds of individual crystals.
- The largest snowflake ever found was 8" by 12". It was reported to have fallen in Bratsk, Siberia in 1971.
- In Germany, frogs were once kept as pets because they croaked more loudly when air pressure fell and when bad weather was coming. They acted like primitive living barometers.
- An ice core 1,200 feet long can show what the climate was 1,400 years ago.
- The lowest ever temp recorded was at Vostok, a research base in Antarctica on July 21, 1983: -128.6°F.
- The heaviest snowfall in 24 hours is 76" at Silver Lake, CO 4/15/21
- The heaviest snow storm occurred on Feb. 13-19, 1959 at Mt. Shasta Ski Bowl, CA: 189" of snow fell.
Scientists believe dust and bacteria blown off plants and thrown into the air by ocean waves produce rain and snow. In a lab, Russell Schnell (U of CO) produced snowflakes by injecting bacteria into a cloud chamber. The experimental clouds immediately turned into snow. The bacteria, Pseudomonas syringae and Erwinia herbicola, contain a molecule that attracts water. After one ice crystal forms, it splinters. Each fragment serves as a seed for another ice crystal. The snowflake’s six-sided shape comes from the hexagonal lattice structure of an ice molecule.
Wilson 'Snowflake' Bentley (1865 - 1931), known as The Snowflake Man, said of snowflakes in 1925, "Under the microscope, I found that snowflakes were miracles of beauty; and it seemed a shame that this beauty should not be seen and appreciated by others. Every crystal was a masterpiece of design and no one design was ever repeated., When a snowflake melted, that design was forever lost. Just that much beauty was gone, without leaving any record behind."
