They are bounds lines, if you cross them you have gone out of bounds. Edit: I'm not sure exactly which lines you are referring to, but snow competitions often have paint on the snow surface at various places to give depth definition to the athletes. Looking at a large white bright surface makes it difficult for your brain to exactly judge how soon you will land, if you are in the air at the time. Painting lines on the snow (or scattering leaves) lets you judge the distances much easier. If they were skiing and riding over these line though out the course then that's what it was for.
Of course.
