Cygnus X is one of the most complex areas in the sky. This complicatesinterpretation, but also creates the opportunity to investigate accretion intomolecular clouds and many subsequent stages of star formation, all within onesmall field of view. Understanding large complexes like Cygnus X is the key tounderstanding the dominant role that massive star complexes play in galaxiesacross the Universe.  The main goal of this study is to establish feasibility of a high-resolutionCO survey of the entire Cygnus X region by observing part of it as aPathfinder, and to evaluate the survey as a tool for investigating thestar-formation process.  A 2x4 degree area of the Cygnus X region has been mapped in the 12CO(3-2)line at an angular resolution of 15" and a velocity resolution of ~0.4km/susing HARP-B and ACSIS on the James Clerk Maxwell Telescope. The star formationprocess is heavily connected to the life-cycle of the molecular material in theinterstellar medium. The high critical density of the 12CO(3-2) transitionreveals clouds in key stages of molecule formation, and shows processes thatturn a molecular cloud into a star.  We observed ~15% of Cygnus X, and demonstrated that a full survey would befeasible and rewarding. We detected three distinct layers of 12CO(3-2)emission, related to the Cygnus Rift (500-800 pc), to W75N (1-1.8 kpc), and toDR21 (1.5-2.5 kpc). Within the Cygnus Rift, HI self-absorption features aretightly correlated with faint diffuse CO emission, while HISA features in theDR21 layer are mostly unrelated to any CO emission. 47 molecular outflows weredetected in the Pathfinder, 27 of them previously unknown. Sequentiallytriggered star formation is a widespread phenomenon.
