This is taken from Canadian Avalanche Assosiation -Size 1 avalanches are relatively harmless to people. They typically have: a mass of 10 tonnes a path length of 10 metres an impact pressure of 1 kiloPascal -Size 2 avalanches could bury, injure or kill a person. They typically have: a mass of 100 tonnes a path length of 100 metres an impact pressure of 10 kiloPascals -Size 3 avalanches could bury and destroy a car, damage a truck, destroy a small building, or break a few trees. They typically have: a mass of 1000 tonnes a path length of 1000 metres an impact pressure of 100 kiloPascals -Size 4 avalanches could destroy a railway car, large truck, several buildings, or a forest area up to 4 hectares (~10 acres). They typically have: a mass of 10,000 tonnes a path length of 2000 metres an impact pressure of 500 kiloPascals -Size 5 avalanches are the largest snow avalanches known. They could destroy a village or a forest area up to 40 hectares (~100 acres). They typically have: a mass of 100,000 tonnes a path length of 3000 metres an impact pressure of 100 kiloPascals

That scaling system has tickled me for some time. I am really not sure if I can perceive the difference in snow force required to damage a small truck, but not destroy a railway car. It just isn’t a sense of force that is native to my mind.

Scary stuff, avis. ..the Blizzard of Aaahhs, a GREAT movie!!...Went and saw Touching the Void last weekend. I shXX you not, a must see movie. They shot on location, parts of it anyway, around Chamonix… I’ve always liked suspense-thriller flicks. Having mother nature as the source puts new meaning into the genre of film...Haven’t seen a good flick like that in quite some time.. Ran into Plake skiing at Kirkwood about 15yrs ago. Cool guy. Was skiing down the Wall when I noticed a few – at the time, thought they were pretty damn awesome – dudes just taking HUMUNGOUS air off the top of the huge cornis along the ridge to the right. turns out they were warming up for a shoot. I came down one run and Plake, takin a breather, said something to the effect, hey man, we’re going to be shooting and so ll be closing this area off, or something like that. Thought, cool..so such was my brush w/ a ski legend..Scott Schmidt also used to make in person appearances at ski movie screenings, etc. A real low key, down to earth, real cool guy.…I’m dating myself, but still think Scott Schmidt is and has always been one of the BEST, true, pure, smoothassmXXaXXXXin SKIERs of all time, here on this planet. He is one smooth skier. ..all this really doesn’t have a lot to do w/ avis and sort of went off on my own tangent - sumimasen - but noticed an article on CNN: http://edition.cnn.com/2005/US/02/16/extreme.skier.death.ap/index.html Rip, Alec.

an oji san?? you're still a pup, Serre. It sounds like you just happened upon a really bad movie.. don't know if you'd be able to find a copy anywhere, but keep an eye out for Aaahhs, released, either in the late 80s or early 90s. Greg Stump was the filmaker. a true classic. Peace.

Telleboy has some scary tales to tell about Avies, havent seen him around the forum for a while.
Plake style? I am guessing it refers to the crazy mohawked extreme skier Glen Plake.

Hey Snowglider, Im still alive and kickin. Been way to busy to spend time on the forum. Im clockin about 60 - 70 days skiing so far. North side of Happo was sick today, a good 30cm of fresh from yesterday, FatTwins tracks out there showed he had a good time today too. He poached alot of the lines before me, was runnin abit slow after yesterdays awesome day. Ive been caught and buried 2x, they sucked, nearly pissed my pants in the first one, I had good friends, they dug me out fast!
