The KPNO video camera system was used to obtain a color-magnitude diagram for the distant halo globular cluster Pal 14. Like other outer halo systems, this cluster has a predominantly red horizontal branch. If M(V) = +0.6 for the horizontal branch stars, then (m - M)0 = 19.4, and the cluster lies 70 kpc from the galactic center and 50 kpc above the galactic plane. The giant branch stars are also red, which indicates an intermediate rather than a low metal abundance for this cluster. An Fe/H ratio of -1. 55 + or - 0.25 is estimated from the dereddened color of the giant branch at the level of the horizontal branch. The implications of this result for the problem of the size of the abundance gradient in the halo of the Galaxy are considered.
