Frazil Ice Makes Stream Disappear Before Your Eyes
Rare frazil ice was caught on camera freezing through a stream in Squamish, B.C., Canada, on December 27, and posted on Twitter by Brad Atchison.
Frazil ice occurs when small, needle-like ice particles form in supercooled water (when water is below its typical freezing point but remains a liquid due to its turbulent flow), according to the Connecticut River Conservancy. Because these ice particles are random and not attached, frazil ice is not solid and looks more like slush along the top of the water.
Squamish and its surrounding areas, including Vancouver, have seen record-breaking cold temperatures over the past week. According to the Daily Hive, Squamish had a temperature of -15ºC (5ºF) on December 27, breaking the same-day record of -12.8ºC (approx 9ºF) in 1968.
