Skim a Pond

Last Friday I went skiing at Arapahoe Basin. Yes, there's still snow up there - but the warm weather is melting it, resulting in conditions known as Spring skiing. The water from the melted snow collects in valleys and trenches, forming ponds excellent for skimming.

Skimming is skiing on water. To skim a pond, the upward force from the skis must exceed the skier's weight, and it must continue to exceed his weight until the skier gets across the pond. The force is determined by the skier's forward velocity, the surface area of the bottom of his skis, and the angle of his skis.

On Friday when I visited Arapahoe Basin, I skimmed a few ponds. It's lots of fun, as long as you don't slow down too much halfway through the pond. Here's a video from my trip:
