@ fossil, you're probably thinking of Hanna Parikka, Class of '96. Also Petr Vohralik from the Czech Republic, I think Class of '98. Both orienteers were foreign cadets, fully-enrolled members of the Corps of Cadets that were nominated by their home countries. I think that process is at least as complicated and demanding as getting a nomination in the US, if not more so.
@tariksea, there are a few orienteers from Cascade Orienteering Club at the University of Washington in Seattle, WA. But for the most part, juniors in the US tend to plan either to go to school in an area with an active club, or to go to the school they can afford while setting aside funds to travel for orienteering. Not only are there no scholarships for orienteering, but not much in the way of college clubs/teams outside of the U.S. Military Academy (West Point) as mentioned above.orienteeringusa.org
has an interactive map if you want to look at areas with active clubs. Lots of universities to choose from!
