  We present a determination of the thick disk iron abundance distribution
obtained from an in situ sample of F/G stars. These stars are faint, $15 \simlt
V \simlt 18$, selected on the basis of color, being a subset of the larger
survey of Gilmore and Wyse designed to determine the properties of the stellar
populations several kiloparsecs from the Sun. The fields studied in the present
paper probe the iron abundance distribution of the stellar populations of the
Galaxy at 500--3000pc above the plane, at the solar Galactocentric distance.
