Last year they closed on September 1st. The north side is all owned by a forest company that requires specials passes to get in that cost a few hundred. I don't have the map in front of my by there is a creek that name starts with a B (I think) that is the border between state and forest company land. Long hike in from the blue gates. Hope this helps.... I know it's kind of scattered.
I'll try to answer some of your questions. The gate was closed on the Elbe town access road last year on Sept 1. I wouldn't use that as a given for every year since logging and road conditions can vary from year to year. Scott-Turner road is always open but access is limited by snow later in the season. The DNR access roads from Scott-Turner rd are all gated about the same time as the Elbe town gate. You can still hike, or bike in and camping is allowed.The eastern boundary of the DNR land is the Busy Wild river. There was a lot of logging done in that area last year. The logging was around the lower portion of the snow park access road accessed from Stoner road, don't turn at the ATV park, just stay on the main road. I don't know how far down they logged but I plan to scout that area this year.Good maps of the DNR boundaries are hard to find but you can get a lot of info on-line. Try this for a start:http://www.dnr.wa.gov/Publications/amp_fl_map_pierceco3.pdfThe NF maps show state owned land as well.
Just one more point to add- no Discover pass necessary if you're parking on a road outside of DNR lands and hiking or biking in. You would only need the Discover pass for your vehicle if you are driving into (or parking on) the DNR land.
