Detailed observational results of the high-velocity CO gas and an associated quiescent molecular cloud in the recently discovered CO outflow source NGC 2071-north in L1630 are presented. The distribution of high-velocity CO wings indicates an extended outflow whose dynamical age is 170,000 yr. The driving source of the outflow is an IRAS source having a luminosity of 40 solar. The associated quiescent cloud has a mass of 300 solar and a kinetic energy comparable to that of the outflow. It is suggested that the outflow may be supporting the cloud against gravity, preventing mass accretion and reducing the star formation efficiency. 26 references.
