At 2 min Alexander skis down a short mountain strip with plenty of snow. Minutes later when Marty and Byron do the same thing there is a huge patch of ground with no snow.
At 4 min the clothes Marty and Byron are wearing at the top of the mountain do not match the clothes they are wearing after they ski down. The color of Marty's pants turns to black from gray. Byron's gloves change from black to gray and the embroidery on his hat has changed.
