Mainly clear or packed snow (2WD accessible with care) from 285 to just south of Duck Lake closure. AWD/4WD was needed for two drifts within the last mile or so to the closure, including one right before the closure that my 4WD Explorer got stuck in. You can park before that drift and walk. From Duck Lake closure to trailhead is fairly clear, with post-holing 7-10 inches deep in 2 or 3 sections of 20-30 yards. Took less than an hour to get from closure to trailhead.
Word of caution - saw some mountain lion tracks on the way from closure to trailhead, and actually had one cross the road in front of me prior to reaching the trailhead. This was in the (very) early hours of the morning.
