Check out this cool map of Arapahoe Basin from 3DSkiMap™, a website that aims to match skiers with the best trails for their ability. The yellow and red areas show the steepest parts of the mountain, while the green and blue coloring corresponds to the easier trails. For Arapahoe Basin, the lower part of the mountain is relatively flat, but check out the steeps off of the East Wall, part of A-Basin's hike-to terrain. Sweet!
Per the website:
"A 3dSkiMap is a 3-dimensional model of a ski area with an image overlay having the steepness or slope of each point coded with a color from a graduated scale, with green designating the least amount of slope, changing gradually through blue, to red, to yellow which designates the highest amount of slope. An orthographic aerial photo of the ski area overlays on top of that to show the location of wooded and impassable areas, as well as man made features. The overall effect is to give the user a general idea of the steepness of an area at a glance, and to give a clear picture of the changes in steepness of a particular trail or piste."
