As part of the Spaghetti Project Survey ( SPS ) we have detected a concentration of giant stars well above expectations for a smooth halo model .
The position ( l \sim 350 ,b \sim 50 ) and distance ( \sim 50 kpc ) of this concentration match those of the Northern over-density detected by SDSS ( 35 ; 18 ) .
We find additional evidence for structure at \sim 80 kpc in the same direction .
We present radial velocities for many of these stars , including the first published results from the 6.5m Magellan telescope .
The radial velocities for stars in these structures are in excellent agreement with models of the dynamical evolution of the Sgr dwarf tidal debris , whose center is 60 \arcdeg away .
The metallicity of stars in these streams is lower than that of the main body of the Sgr dwarf , which may indicate a radial metallicity gradient prior to disruption .
