Planning a downhill ski resort

So, we are planning to build a small downhill and x-c ski center on campus. In this exercise for Site Planning Studio, we are working with the area we call the North Campus, downhill and north of the new dorm.

This area was the site of the former Sheraton Inn and a public swimming pool when our Foundation purchased the property some 10-15 years ago.

Since the slopes (ski runs) face generally a northerly direction, why not put in some ski trails?  The north slope will have shade.  We can use one of the many sunpath diagrams to identify the solar path and impact on the snow cover.  Try this one for size.
