New high dynamic range (1000-2000) radio continuum maps were obtained for two regions of vigorous star formation, G10.6-0.4 and W33. The morphology of an extended low-level ionized emission component is successfully defined. Ionized gas due to an earlier epoch of star formation appears to flow around and fill in between dense neutral condensations. Bright rims are found facing toward the central continuum core where the most recent episode of star formation is taking place. This supports a model where radiation-driven ionization shock fronts from first-generation OB stars lead to the efficient implosion of nearby neutral condensations and the formation of second generation stars. 22 references.
