I agree with Dave, and note that I've seen "closed" markers at Coyote Call/Rabbit Ridge and Corral Canyon/Calzada trailheads. I did not notice closure at Upper Frijoles loops, which are pretty flat, but which, based on Los Alamos conditions, probably have good, deep snow now.  Further west on NM4, the Los Griegos and East Fork trail areas were not closed last week. From the western East Fork trailhead, the track is steady uphill, but not steep.  If you try the NM4 trailheads, the parking areas were not plowed last week.  We've had a lot of snow herein Los Alamos, and I'm not trying those area until I get new tires. 

Another possible option is the trail network west of the Pajarito Mountain downhill area.  It's accessible from the west end of the parking area there.  It's maintained by the Southwest Nordic Ski Club, but is open to the public. It is frequently groomed, but if you ski far enough west, it leads to Canada Bonita and points further west. It's popular, and there is frequently a track that leads out across this meadow and beyond.
