The galactic anticenter region contains several streams of high-velocity clouds of HI. The principal stream is associated with a localized HI feature at forbidden negative velocities near ℓ, b = 197°, 2° (Weaver 1970, 1974). Here we show that the forbidden-velocity feature, in addition to being the culmination of three streams of high-velocity clouds, is correlated with a disturbance in the permitted-velocity gas. Evidence suggests that this disturbance is located within the Galaxy, implying by association that the anticenter high-velocity clouds and the culmination feature are at distances interior to the Galaxy.
