We report and analyze CO spectra of NGC 2071 which exhibit broad wings and prominent self-reversed line profiles. These wings provide evidence for high-velocity bipolar gas flow powered by a strong stellar wind along the axis of a disk. The self-reversed line profiles are due in part to radiative transfer effects in the main body of the cloud, which may be contracting; however, a significant amount of self-absorption also originates in cooler foreground gas at the cloud periphery.
