We present results from 5.5 square degrees of deep imaging in DLS fields F1 and F2 with NEWFIRM, in the J (1.2 micron) and Ks (2.2 micron) bands. The combination of deep optical and NIR data will allow us to improve weak lensing mass maps through improved photometric redshifts, identify cool dwarf stars to unprecedented distances extending into the galactic halo, and study the high redshift universe with Lyman break galaxies, high-redshift radio galaxies, and quasars. The DLS is wider than any survey of equivalent depth, and deeper than any survey of equivalent width, allowing the study of rare faint populations of all kinds in a multi-wavelength data set now including X-ray, optical, NIR, and mid-IR.
