Mt. Bachelor is fully open again today, after an avalanche closed part of the mountain Wednesday. Spokesman Andy Goggins says a resort guest reported the avalanche at 10 a.m. and the resort's Avalanche Team responded to make sure no one was injured or trapped under the snow. “There we no victims reported to be caught in the slide. But the Mt. Bachelor Ski Patrol kept that area closed and proceeded to run a full search procedure, including the use of our avalanche dogs.” It occurred near the top of the Skyliner Express chairlift. Weather experts say the recent quick change in temperatures and a large amount of snow are prime avalanche conditions. Ken Boone with the Weather Channel:  “You know every time it snows and you get a new layer of snow on top of each other, the bond in between the layers isn’t necessarily always strong. Sometimes if you get a weak enough bond in between those packs of snow maybe you get a lighter snow and then you get a heavier snow on top of that. That bond in between the two different layers could cause an avalanche as well.” Boone says steep terrain is another avalanche factor. So if you're going out in the back-country he suggests that you're constantly aware of the weather conditions and forecast; and your immediate surroundings.
