Abstract: Chemical abundances for twenty one elements are presented for four red giants in the anomalous outer halo globular cluster Palomar 1. The mean metallicity, [Fe/H] = –0.60 ± 0.01, is high for a globular cluster so far from the Galactic center. In addition, its [α/Fe] and neutron capture abundances seem to indicate an origin in a dwarf galaxy, although it is not definitively associated with any known streams.
