CG2000, off of Foster Creek Road has a new gate and a "road closed" sign blocking access to the Rock Creek trailhead at 45° 43.3671' N, 121° 56.0531' W. The road is freshly graded, too, so I imagine that WA DNR sold the timber on the public land or the LLC that blocked CG2020 with a gate put this one up, too.
Access to the trailhead may be available via W-2000 on the west side of TRC.
