Blog: The Brett Kobernik Skunkworks
Bruce Tremper
I dropped a vehicle off at Brett Kobernik's house yesterdayand caught him working in his garage. I thought others would be amazed, as I always am,in a look behind the scenes ofthe skunkworks of the Utah Avalanche Center and the genius of Brett Kobernik. Here, on the left, he has a couple of motorcycles converted into snow bikes with a snowmobile track on the back and a ski in the front.

Drew Hardesty
Guilt from Drew Hardesty on Vimeo. A few years ago, one of my best friends was caught in an avalanche somewhere north of here. The avalanche was triggered from above - another skier on the slope - and as the Leviathan roared down, he pushed another skier out of the way toward safety...and suffered the onslaught of the avalanche.

Blog: Drift into Failure...or, Mathematics and a Few Thoughts on Risk
Drew Hardesty
What is your Level of Acceptable Risk? How did you determine this? Some will center-punch Superior on a CONSIDERABLE danger while others feel happy going to Powder Park everyday. Everyone is different and it's insulting at worst and a waste of time at best to look askance at others who are on either end of the pendulum. It's - how shall we say - inelegant to look upon some as suicidal and others as boring and unfulfilled.
The key points here are
To be aware of your level of acceptable risk
Understand factors that may influence your risk …
