Abstract

We have adopted a detailed map in the CO J=3-2 line of the M17 molecular cloud complex covering an area of about 60 square arc minutes. As well as the M17SW cloud core, the map covers the areas containing both ionization bars, and their surrounding molecular clouds. A complex dynamical picture will be presented, with evidence for fragmentation of the complex into a number of discrete clouds, as well as indications of wide-spread interaction between the ionization bars and the CO gas. The morphology revealed by the CO maps will be discussed in connection with the distributioins of IR, radio and optical emission, and the overall dynamics of the whole M17 region.
