We present the first data release of the Bolocam Galactic Plane Survey (BGPS) and a sample of its early results. The millimeter dust continuum is an excellent tracer of the matter most intimately associated with star formation, and the BGPS is one of the first large area, systematic surveys of the Galactic Plane in the millimeter continuum. We have surveyed 170 square degrees of the Galactic Plane including the full first quadrant to latitude +/- 0.5 degrees. The BGPS team has detected 8500 'clumps' and initiated followup heterodyne observations of thousands of these. Detailed studies of outer Galaxy regions W5, L111, and GemOB1, Infrared-Dark Clouds (IRDCs) in the inner Galaxy, and the Galactic Center have provided early measurements of the clump mass function. We have detected CO outflows associated with a significant fraction of the BGPS clumps in the L111 and W5 massive-star forming regions, identifying these clumps as actively star-forming. Ongoing studies include observations to determine the star-forming activity of BGPS clumps and directly measure their temperature and density. These studies allow us to determine the physical properties of well-known and previously unknown massive star forming regions throughout the Galaxy. The BGPS was supported by NSF grant AST 0708403.
