too much snow

Hi All,
A few years back in California we had "the Winter of the 40 foot snow". I went up to go skiing. Got to the snow park, climbed the huge pile of snow piled by the side of the road. I strapped on my skis and slid down the hill and onto the flat snowy plain, where I sank nearly to my armpits before coming to a stop with my skis in the snow down there someplace. I managed to wade/crawl back to the hill and get back to my truck.

I was writing to someone in Scandanavia and they said that they use 3-4 meter long skis in deep powder. Anybody know where to buy them or have any alternate suggestions? I once made 4 pairs of snowshoes from welded 1/2" thinwall electrical conduit. I could make some snowshoes about 9 feet long...
