Go up the steep hill on the right at the very start of Jefferson Creek. Head east until you hit an obvious old 4-wheeler trail. Follow that trail and head uphill whenever you see an area you'd like to ski. Terrain gets progressively steeper both the further uphill and the further down the trail you go.
On the way down, you can ski past the trail and cross the creek to get on the hard packed cross country trail that follows the road.
