Where the snowpack is deep it's homogeneous, it's happy in its own skin, and it's generally bomb dot com. But here's the deal... we don't trigger deep, dangerous avalanches from thick portions of snow, rather it's from thin spots, like around bushes or rocks poking out from the snow, or barely hidden under the snow surface and we can't 'em. In either case, with miles and miles of solid snow and predictable avy conditions, you'd have to get very unlucky to trigger a slide that breaks to old, weak layers of snow now buried deep in the snowpack. The usual suspects come to mind... steep, rocky slopes in the wind zone is the kind of terrain we wanna steer clear of.
