Interesting Facts and the Science Behind Snow

1. The world’s largest snowflake: It was reported to be 15 inches across and 8 inches thick. According to the Guinness Book of World Records, this beast of a snowflake was found at Fort Keogh, Montana on January 28, 1887.

 Disclaimer: Not the largest snowflake in the world, but it sure is pretty!

2. Snow is not white: It is actually clear and colorless. As the National Snow and Ice Data Center so eloquently put it,

“The complex structure of snow crystals results in countless tiny surfaces from which visible light is efficiently reflected. What little sunlight is absorbed by snow is absorbed uniformly over the wavelengths of visible light thus giving snow its white appearance.”

3. World record snowfall: Mt. Baker ski area in Washington State has the world record for snowfall at 1,140 inches of snow in the 1998/1999 winter season.

You could've leaped out of an airplane and landed unharmed! Don't try that at home... 

4. Six sides or bust: All snowflakes must have 6 sides otherwise they are not considered snowflakes. In a nutshell,

"The laws of electronegativity and molecular bonding between oxygen and hydrogen atoms dictate that the formation of positive and negative dipoles causes H2O to have a V-shape. Intermolecular forces between the oppositely charged ends of different particles cause them to join together in a very specific three-dimensional pattern with a six-sided symmetry."

L.A. Auto Show Witnesses Debut of 2015 GMC Yukon and Yukon XL

The middle child of General Motors' trio of truck-based SUVs, the GMC Yukon and long-wheelbase Yukon XL, received their auto show debut at the 2013 Los Angeles Auto Show. Showing off a bigger, bolder look, particularly on its Denali trim, the Yukon sports prominent chrome grille instantly identifies GMC's new top-end SUV.

The Yukon is will come to market with a pair of engines. The base 5.3-liter V8 pumps out 355 horsepower and 383 pound-feet of torque, while the higher-end models benefit from the same direct-injected, 6.2-liter V8 as the Escalade. That engine makes 420 horsepower and 450 pound-feet of torque, with fuel economy seeing a likely boost thanks to an active fuel management system. Like the Tahoe, Suburban and Escalade, the Yukon takes advantage of a six-speed, column-mounted automatic transmission.

The cabin has seen significant upgrades in terms of materials and technology, with an eight-inch touchscreen display and IntelliLink standard in both Yukon and Yukon Denali. Fold-flat second and third-row seats come standard, while a power option is available, as well. Other techy features include active noise cancellation and standard Bose stereos.

You'll be the envy of everyone else on the road in one of these beastly rides!
