20km track-set for classic in winter 2014. 

The Billy Lewis trail map gives a good overview of the area.  

The main trailheads are at Denton Hill and Ski Denton, a downhill ski area with a snack bar, and xc trail access via Elm Hollow Trail (a mile and half climb) or by purchasing a one time lift pass.  Grooming at Patterson State Park has been halted temporarily (winter 2014) due to timber-logging activity.
