 Welcome to your Janurary Ninth edition of CNN Students News, I'm Carl Azuz. In less than a month, the 22nd Winter Olympic Games were taken off in Sochi, Russia. Opening ceremony is Friday, February 7th. Here's the by the numbers look at what's ahead: 6000 athletes competing, the best in best in Winter sports from 85  countries worldwide. The Olympics will round 17 days in the resort city, they'll include 1650 Paralympians and they'll be traveling to Sochi from 45 countries. Total number of events, 89, some of them will take place near Sochi's coast, others in the mountains overlooking the city. This could be the most expensive Winter Games ever. Russia's spending at least 50 billion dollars on things like roads, railways, stadiums, ski jumps and security. Russia says this will be the most secure Olympics ever, 25000 police officers, 8000 additional security officers. The country is confident in Olympic safety, and that's the despite reason terrorists bombings in another Russian city. And this could be the warmest games ever. Sochi's average temperature in February, 47 degrees Fahrenheit.  It's colder than in Vail, Colorado, one of America's largest ski resorts. It has  some of the best skiing in the US. In Vail's back country, a way from the mountain itself, the terrain is only for the most experienced skiers and snowboarders. There is an avalanche control here and two skiers and two snowboarders got caught in a sudden slide of snow Tuesday. Three of them were temporarily trapped. The fourth person, the grandson of one of the Vail's co-founders was killed. Officials believe the avalanche was caused by the skiers and snowboarders. Conditions might have been right for one. 

 
What we've been seeing over the last, say, ten days or so,  is just a general increase in the size of the valances in the back country. 
Why is that?
 
Well, we have some very weak snow near the ground that formed early in the season, and we've been getting kind of consistent snowfalls, so the slab over it and starting to get fickler and larger. 
 
Skier Davis Lamer recently rescued his brother from an avalance in the same area. Clearly shows you how quick and dangerous these events can be.
