Right out of college I spent a winter living in that little cabin
settlement at the west end of Donner Lake, CA. It was a heavy winter,
lot's of snow. They plowed the bigger roads and made huge berms like
that.

It was GREAT FUN to take your disposable "snow car" out on the icy
roads, hit the brakes, crank the wheel, and carom down the road,
spinning and bouncing off the vertical berms like you were in a pin
ball game.
