Description
A survey of 380 sq. deg. of the sky with the 1m Schmidt telescope at the
Observatorio Nacional de Llano del Halo and the QUEST camera has found
498 RR Lyrae variables lying from 4 to 60 kpc from the Sun. We describe
the halo substructure revealed by these data and the results of
measuring some of the stars' radial velocities and metal abundances.
