Piles of Snow

These photos are mostly for those who live in more southern climes. Those who live in the interior of BC have seen it all before. Because McBride is a small village we don't have any really large parting lots that need to be cleared of snow, and when we do go up to Prince George in the winter, I am always a little surprised at how high snow piles are. How do they get them piled so high?
I parked my truck in front of the one pile so you could get a sense of the scale.
