Define: Exposure
Exposure refers to the clearly visible rocks on a mountain that is covered with snow. When a snowboarder rides down a mountain with alot of rocks that rider would be doing a line with alot of exposure.
Xtreme snowboarders like Steve Klassen ride steep lines with alot of exposure in contests such as the Verbier Xtreme Freeride contest in Verbier Switzerland.
Pete Scheira and Trevor Stewart snowboard through a line with a ton of exposure.
