The magic and science of snowflakes

 



Snow is, of course, also essential to our rivers and water supply. The 40 million people in the Colorado River basin, and the vast agricultural network that we take for granted when we shop for groceries, depend on winter snowpack. Summit snow fills reservoirs with essential spring and summer water.

We hear a lot about how many inches of powder we can expect, and we plan our days around those predictions. But how many snowflakes actually fall in these storms? Many billions of these spectacular crystals create a snowfall. One pound of snow has an average of 22,400 snowflakes. And each snow crystal is an incredible work of science and art.

How do these spectacular snow crystals form? Snow crystals generally are hexagonal (six-sided) due to the way they form. And they’re not frozen raindrops (those are sleet). Snow crystals appear when water vapor converts directly into ice without going through a liquid state. Water molecules in ice crystals join together in a hexagonal structure because it is the most efficient way. After the crystals form a small hexagonal plate, branches sprout from the six corners as the crystal grows larger and more complex.
