The authors present 21 cm aperture synthesis observations of the continuum and H I line emission of a 2° field centered on the H II region S142. The total continuum flux from S142 is 13.3 Jy, and the peak emission measure is 15,800 cm-6pc. A simple model of the ionized gas density distribution yields a total ionized mass of 4000 M_sun;. Several H I emission features related to S142, forming a partial shell around the H II region, appear to be gas which has been dissociated by the exciting star. The total mass of H I, ≡3000 M_sun;, greatly exceeds the mass of molecular material present (≡200 M_sun;). DH Cep, the exciting star, is contained in a young open cluster, NGC 7380. The evolutionary history of the cluster/gas complex is outlined.
