High-spatial-resolution maps of G333.6-0.2 in both Ne II line and infrared continuum emission at 12.5 microns are presented. The distributions are remarkably similar showing a simple compact and nearly symmetric source. A model of the region is presented which satisfactorily accounts for the observed infrared spatial distributions and the radio observations, and indicates that a significant fraction of the dust heating arises from the absorption of Ly-alpha radiation. In the compact core the dust is depleted with respect to the gas by a factor of 100, and in the outer regions by a factor of 10, compared with the interstellar dust/gas ratio.
