We propose to obtain griK imaging with the SOAR telescope of 10 members of a flux-limited sample of millimeter-bright point sources discovered in 1250 deg^2 of South Pole Telescope survey data-with the eventual goal of imaging the full sample of 48 sources over several proposal cycles. These rare sources are the brightest members of the dusty, star-forming galaxy population, and both theoretical calculations and an intensive multiwavelength followup campaign (including SOAR and space observations) indicate the majority of these sources are at high redshift and strongly lensed. The magnification and the long-wavelength selection makes these sources the best window we have to directly investigate massive galaxy formation in the early universe. Our proposed observations to image the environment, characterize the lens, and in some cases detect the lensed source, are the first step towards fulfilling the scientific promise of this exciting new class of sources. The long-term legacy of these observations will be to provide the astronomical community with a sample of high-redshift, strongly lensed systems for detailed studies with Herschel, ALMA, and JWST.
