Today's creativiti on the ice

I thought the family and I were just going to walk on the ice and look around, get some exercise. We did that and found some rough and smooth patches so we could get some speed and then slide. My son also suggested an artwork challenge. We had three duels; son and I, wife and I, son and wife. None of us managed anything fantastic and I will not tell you whose art you are looking at, but we had fun.  The challenges were boat, helicopter and tree.

 To me, the way the snow drifted and hardened resembled topographic maps. There were low, dark spots with only a dusting of snow over the ice. There were also thicker, brighter areas of thicker snow. The thick areas were larger so they appeared to me to be mainland around lakes with islands. You are welcome to invert the concept so there is dark land surrounded by bright seas.
