[pct-l] Campsites near Timberline Lodge?

[CClark]

Is anyone familiar with campsites in the vicinity of
Timberline Lodge? 
On Half-mile’s maps, I see a campsite just before Timberline
Lodge at mile 2105.3.  Via Ramona Falls
Trail, the next campsite I see is Sandy River at mile 2117.  I’m assuming this is a heavily traveled area,
so there is probably no camping available or allowed between those two campsites.  Is that correct, or are there other possible
campsites not shown on Halfmile’s maps? 
Thanks,
