A high angular resolution map in (C-12)O has been made of the large globule L810 which reveals an outflow associated with a cluster of embedded young stellar objects and a water maser. It is argued that two stars are responsible for the outflow. The morphology of the regions of redshifted and blueshifted high-velocity emission resembles that of a biconical flow model, with both cones intersecting the line of sight and each cone producing both blueshifted and redshifted emission. This is the first outflow identified with this flow geometry. The high-velocity gas is very optically thick in (C-12)O and is clumpy with beam filling factor around 0.4 in the central part of the outflow region. The mass of the globule with a radius of 2 arcmin is estimated to be 300-600 solar masses. The total mass of the globule is about 750 solar masses. 38 refs.
