In 1887 , a rancher named Matt Coleman distinguish huge snowflakes that had fallen onto one of his kine pastures in westerly Montana during a snowstorm and declare them as " larger than Milk River Pan . "
With a width of 15 inches ( 38 centimeters ) and a heaviness of nearly 8 inches ( 20 centimetre ) , these colossal flakes presently hold the record for being the largest snowflakes ever recorded , agree toGuinness World Records .

Despite there being no photographic evidence of the giant - size of it snowflakes , they stay a pop piece of hurry small beer . But it does raise the question : Is it even potential for a single snowflake to form to be the size of a dinner plate ? And , what ’s the grownup a snowflake can really get ?
Kenneth Libbrecht , a purgative prof at the California Institute of Technology , say such monster flakes are rare but not impossible . That ’s because there ’s a common misconception of what makes a flake an actual snowflake .
When people speak about snowflake , what they ’re actually name to are snow crystal , which are single crystals of ice within which the water system mote line up in a hexagonal approach pattern that causes them to " display that characteristic six - fold symmetry we are all familiar with , " Libbrecht tell Live Science .

snow bunting , on the other hand , can encompass everything from an item-by-item nose candy quartz to hundreds or even thousand of snow quartz that nail and hold fast together in midair as they fall to the ground to form clump or aggregate .
In insensate blank space , " you see them all the prison term , these bountiful true puffball falling out of the sky , " Libbrecht said , " They ’re not blow crystals ; people call them Plectrophenax nivalis , but I like to call them puffballs because that ’s more indicative of what they ’re shaped like . "

So , it ’s possible that the infamous gobs that Coleman saw on his cattle ranch more than a C ago were simply a bunch of chicken feed crystals that had collided together to form one mass snowflake .
However , the typical size of it of a snow crystal is far smaller .
After spending much of his career studying and photographing snow crystals , including writingseveral booksand creating awebsitededicated to the topic , Libbrecht said that the largest snow crystal he ’s ever spy in the wild was a " monster . "
" It ’s the biggest one I ’d ever view , about 10 millimetre , [ 0.4 inches ] " Libbrecht said . " It was about as adult as a dime bag . "
Inhis science lab , under operate status where there ’s no steer to shred snow crystals apart in midair and temperatures can be arrange to an ideal 5 degrees Fahrenheit ( minus 15 grade Anders Celsius ) — gross for snow lechatelierite formation , Libbrecht said — he ’s " easily reckon " crystals grow to similar size .
" That ’s about as swelled as they get , " he said . " I ’ve been studying this for a while and I know a batch of other snow bunting photographers , and we equate notes . Ten millimeters — that ’s a vainglorious one . "
The intellect snow crystals top out at that size is due to the wind .
" The main limit on size is just that these large crystal are quite fragile , " he said . " They have to produce rapidly , and if there is any breaking wind they break asunder . So the weather conditions for making such large crystals are rare . "
Although snow crystal may be small in stature , the variety of shapes they can take on is astounding . In the thirties , Ukichiro Nakaya , a Japanese physicist who produced the world ’s first artificial snowflakes , documented their many different shapes in amorphology diagram , which , count on the temperature and humidity at which they form , can range from simple prisms and columns to more detailed rosette and fernlike prima dendrites .
— Why is snow lily-white ?
— Why do clouds float ?
— Why do we shudder when it ’s cold ?
For representative , six - armed dendrites begin forming at below freeze while columns take shape at around minus 10 degrees Fahrenheit ( minus 25 degree Celsius ) .
" When you grow them in the lab you may see what pass off under unlike experimental condition , " Libbrecht aver . " It ’s unmistakably diverse growth . Not all crystals grow under such a diversity of shapes , that ’s kind of unparalleled to trash . "
