My understanding of the T-6 crossing is that it is at the point where Hook Creek Road crosses Deep Creek. Hook Creek follows Hook Creek Road. Down near the bottom of this road, Hook Creek Road crosses Hook Creek and then the road turns to dirt and continues on a short relatively short distance to Deep Creek where the road crosses ( 4 wheel drive only ) and continues on as another number route. Best I can see, that crossing is the T-6 crossing. The USFS rule says no nudity within a quarter mile of that crossing. DCHS is a long ways from there so people hiking around the hotsprings need not worry about the T-6 crossing.
