Its properties can vary with time and with depth in the snow pack. The conditions needed to allow snow rollers requires a thin, moist and cohesive layer sitting loosely atop a firmer layer.<\/p>\n<p>The way to think about it is to picture a thin layer of cookie dough that is initially rolled flat on a floured breadboard. If an edge of the dough is lifted and pushed, it can be rolled up. For snow, the wind does the lifting and initial pushing, but on the mountain slope, gravity keeps it going.<\/p>\n<p>Some snow rollers on Mt.
