Skislope challenge

[Yannick]

With global warming and all, more and more skislopes in touristically highly developed mountain regions worldwide are lacking the amount of snow they require. For this challenge, let me ask you to design a track with extreme altitude changes, that leads up one and leads down at least another (then former) ski slope, with the pitlane and main grandstands being located in the valley below. Thanks in advance for your participation.

(Originally, I had intended this to be yet another weird conceptual track for the OtherWorld(ly) Series, but lack of time for researching the subject now influenced me to offer this concept to you. It's a circuit concept that's rather less likely to be built in reality, because of the environmental issue that is caused by sealing off surface in regions with high occurence of rainfall: You don't want to turn your track slopes into new streams during the winter, because they would flood the pits and everything that surrounds them.)
