Inspection of H 1 channel maps having 1' resolution reveal numerous linear and cone-like structures which are abruptly truncated at one end. These structures are typically a degree or more in length, and 30-45' in width. Preliminary investigation of some of these structures suggest that they may form a new class of phenomena: anisotropic flows of atomic material streaming from molecular clouds. An in-depth study of one of these objects suggests that the exciting objects are probably newly-formed stars. If confirmed, this hypothesis suggests that these anisotropic flows may play an important, but previously unrecognized, role in the evolution of star-forming molecular clouds. We are investigating the ubiquity of this phenomenon by compiling a catalog of suspected anisotropic H 1 flows from the available H 1 line data of the Canadian Galactic Plane Survey. Where CO line data is available, we are searching for possibly associated molecular structures. We present preliminary results from this project, derive physical paramaters for identified structures and discuss one object in detail.
