I summarize the current view of the nature of the halo of the Galaxy, which comprises at least an inner halo and outer halo population, each with distinctly different kinematics, spatial distributions, and chemistry, as confirmed both from recent observations and numerical galaxy formation scenarios. These smooth halo components exhibit also a distinct chemical pattern in term of fraction of carbon enhanced metal poor stars (CEMP). Such characteristics will be discussed during this talk together with the possible formation scenarios.
