The combination of spatial and spectral resolution allow us to use Chandra in the study regions of massive star formation which had been inaccessible even from the ground until the last decade. I will survey the state of our understanding by discussing data from 4 moderately massive star forming regions. Three of these are somewhat distant clusters supporting O stars, RCW 38, NGC 281 and RCW 108. The fourth is NGC 1579 which is a smaller cluster centered on the Be star LkH\alpha101. These regions show very diverse and complex environments. RCW 108 is the youngest of these and supports the hypothesis that previously extant density enhancements within a cold cloud are pushed to collapse by the ram pressure from a nearby young star. The O5 star at the heart of RCW 38 is actively compressing a nearby core. We compare the environs of these regions of star formation focusing on changes in the gas to dust ratio and the composition of the dust.
