  I review the properties of the Galaxy's stellar halo, specifically as traced
by horizontal branch stars, but with reference to and in comparison with other
stellar tracers. I discuss the halo density profile, the variation in
horizontal branch morphology with Galactic position, and the kinematics of halo
stars in several regions of the Galaxy. I summarize the horizontal branch star
findings and place them in the context of a currently popular picture of
Galactic halo formation.
