Snow is deeper than the bulldozer
Look at all the snow. It totally dwarfs the large D8 bulldozer. It almost looks like a little toy in that vast sea of snow.
The road to Artist Point is buried in snow that is 20 to 25 feet in most places, and gets even deeper the further up the road you go.
The bulldozer works out in front of the snowblower to cut the deep snow down to 8 to 10 feet deep so the snowblower and then come through and blow it out.
