When heavy machinery does the plowing after a monster snowstorm, the result is some monster piles of snow. Mountains, really.
A. helped Cubby dig out a snow cave at the base of this mountain.
And then Cubby added a drop-down hole from the top.
Their continuous climbing on it has resulted in paths along the sides and a flattened place on the top from which to survey their domain. And blow bubbles.
Every child's dream, right there next to the house.
