A wispy, white substance was lately noticed at a historic website in South Carolina, main some to imagine the objects have been items of trash. However this cotton candy-looking materials was really an uncommon frost formation often called “hair ice,” the South Carolina State Parks introduced Thursday.

“This frost incidence occurs throughout humid winter nights when the temperature drops slightly below the freezing level. The textures and kinds are a results of the fungus Exidiopsis effusa,” the South Carolina State Parks defined on Fb.


Photographs of the hair ice, often known as “ice flowers,” have been captured by a park ranger at Musgrove Mill, the location of a Revolutionary Struggle battle in August of 1780.

The fungus liable for these odd shapes was solely lately decided; a examine launched in 2015 by the European Geosciences Union introduced the fungus Exidiopsis effusa was the “lacking ingredient” that offers hair ice its “peculiar form,” the German and Swiss scientists who made the invention wrote.

The scientists concluded these silky ice filaments are a outcome “ice segregation,” and famous “the identical quantity of ice is produced on wooden with or with out fungal exercise, however with out this exercise, the ice kinds a crust-like construction,” Christian Mätzler, a examine co-author, mentioned in a press release on the time.

Mätzler added the fungus helps the ice to “kind skinny hairs,” which have a diameter of roughly zero.01 mm, or zero.0004 inches, he mentioned. The substance is ready to hold its form “over many hours” with near freezing temperatures.

The fungus accountable was found in 2015 by scientists in Germany and Switzerland.

A scientist named Alfred Wegener was the primary to review hair ice in 1918 and, on the time, hypothesized the fungus was a key element within the formation of the weird shapes. However the reasoning behind the “uncommon and fleeting” phenomenon was arduous to verify for simply that motive, Gisela Preuß, a biologist who contributed to the examine, defined on the time.

“Hair ice grows largely in the course of the night time and melts once more when the solar rises. It’s invisible within the snow and inconspicuous in hoarfrost,” Preuß mentioned, noting it’s sometimes seen in “broadleaf forest at latitudes between 45 and 55 levels North.”

The pictures posted by the South Carolina State Parks garnered 1000’s of reactions and shares — many writing feedback in awe of the icy creations.


“Lived in SC all my life, 70 years, and have by no means seen this. Thanks for sharing,” one particular person wrote.

“So cool! We homeschool and this simply gave us some nice materials to analysis extra for science at the moment!” one other added.

“By no means heard of this. How cool,” a 3rd commented.
