Abstract
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.
