It was open all the way to the turnout at the end of the road (~ half a mile past the ridge to Pine) when I was there in August . . . I don't imagine that has changed since.
(I was surprised to find both Blue Ridge and Guffy camps completely full when I arrived on a Saturday night.)
The ranger station told me Lupine campground but I don't know if she understood what I meant because Lupine is a turnoff from Guffy and not the section that continues to Pine.
