CCD images and UBV integrated photometry of 31 clusters comprising a magnitude limited sample in a remote northern region of the LMC have provided reliable ages and consistent abundances using isochrone ‘fits’ to deep color-magnitude (CM) diagrams for the 15 clusters with CCD data. Ages for the remaining clusters have been inferred from their integrated colors. The resulting LMC cluster age distribution is markedly different from the age distribution of Galactic clusters suggesting a significant ‘burst’ in the cluster formation rate in the outer LMC 2-4 Gyr ago. The age-metallicity relation (AMR) for our LMC cluster sample is also presented.
