Abstract

Presently data from several ongoing surveys, and in particular fromthe Spaghetti Project Survey have allowed us to map substructure inthe halo associated to multiple passages of the Sagittarius dwarf.Future astrometric missions such as GAIA will be able to recover trulyancient accretion, thus providing us with the formation history of theMilky Way.
