A week of off-piste skiing: 1 in 21,000 chance it kills you
~48 micromorts. Like 5 general anaesthetics, or 5 years of office work. Estimate.
Mortmeter: Worth it. Untracked alpine powder is worth fifty micromorts unless you forget your beacon and common sense.
Assuming: 6 days of lift-served off-piste and freeride skiing in the Alps without a full-time guide
How we got this: Ski touring averages 9 micromorts per day, while lift-served off-piste delivers more downhill vertical and exposure per hour. We priced 6 ski days at 8 micromorts per day, giving a total of 48 micromorts.
What gets you: Avalanche burial, Trauma from high-speed falls into rocks or trees, Crevasse falls in glacial terrain.
Cheaper version: Hire a certified IFMGA mountain guide and stick to stable snowpacks to cut risk by 60%.
Sources and method: how Mortmeter prices things, and the Atlas of measured risks.
More priced risks: Sharing a bottle of Flor de Pingus, Riding Polyppen at Bakken in Denmark, Eating 2 whole pizzas, Drinking a bottle of red wine, Winter bathing in the Øresund, Getting LASIK eye surgery, Texting while driving on the motorway, Cage diving with great white sharks.
