  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.
