What are the dimensions of the 2011 denver dig air ramp?

I'm doing a project for my calculus cl on Big Air skiing and would like to know the exact dimensions of any big air ramp (steepness, launch angle, size of the ramp, etc). I only chose this particular ramp because it is man-made and I figured that there would be more exact information regarding details. Any type of building blueprint or lay-out plan would be ideal.
