Dickson lake to Harrison West?

I'd like to go behind Mission heading Eastward to Dickson Lake and continue on to Harrison Lake West side road, where I'd return to Harrison Hot Springs. DRZ400S, solo, weekend ride.
I searched this site, many did it before calling it Chehalis to Dickson, but nothing as of late. Has anyone ridden this lately? Your experience? Recommendation?
Maybe GPS files for me to follow, but I can plot something out. Thanks.
