What is the average slope for a terrain park?

I am doing a ArcGIS project in which I am choosing the location for a terrain park only area in southwest michigan. I was wondering if anyone knew what the slope for an average terrain park or slopestyle course so I can have some framework to work off of in terms of where I should place the said ski area.

You can figure that out pretty easily using ArcGIS. DEMs are available for damn near every square meter of North America for free. Find a DEM for any representative set of mountains. Using the 3D analyst tools, you can trace the trail of each mountain's intermediate park with a 3D line. With the 3D line you can build an elevation profile which, as long as you know rise over run, you can easily calculate the slope between any 2 points.

OP I brought a ruler up to my ski hill and measure my park today. It dropped 2 inches and moved over 7 so your slope is -2/7

You can also use a topo and trig to figure it out, but I dont know how accurate the distance between the two elevation points will be.

I can get you some actual data from Killington or Mount Snow this weekend if you care enough haha.

I do some dirt work design for parks so I spend a lot of time measuring slope angles. The best terrain for park building is surprisingly flat. A lot of parks are not built on an ideal pitch. This is usually overcome by changing the design of the features. If you had the luxury of choosing the pitch, 12 degrees or even less is pretty ideal for a flowy rail section. For jumps 15-20 degrees makes it easy to build a nice hybrid style jump line.

Damn that sounds like a sick job. Who do you work for?
