Early last week, around 45 megatons of ice and rock plunged down the southeast flank of Mount Steele in Canada’s Yukon Territory. The avalanche, which occurred in a remote and unpopulated area, was so large that it was initially detected by earthquake seismometers.
In another reminder that the Red Planet features a complex and active surface, the HiRISE camera aboard the Mars Reconnaissance Orbiter has captured an image of a “dry ice avalanche” streaming down a cliff.
In light of a deadly incident last year at Mount Everest, Nepalese guides have charted a modified route to reduce avalanche risk. Trouble is, it will expose climbers to some extremely challenging – and potentially deadly – terrain.
Oh, and did we mention it's covering the only road out of town? And that the snow has dammed up the river behind it, creating a giant lake?
As part of its research into preventing avalanches, the Institute for Snow and Avalanche Research in Switzerland has a deep understanding of the structure of snow and ice crystals. Which Nestle realized could also be applied to improving the shelf-life of ice cream.
Aimed at winter sports enthusiasts, the Lifebag is a nifty refillable backpack. Weighing in at less than three pounds, its 150-liter capacity tank fills with gas in just three seconds when inflated manually, protecting the head and upper body of the wearer.
