Resumen: We present a multi-frequency study of HH 137 using Gemini images and APEX molecular line data, as well as Spitzer images. Several 2.12 m knots linked to HH 137 are identified on the Gemini image. CO(3-2), CO(3-2), and CO(3-2) line data reveal the molecular counterpart of HH 137. Spitzer combined images suggest the location of the exciting source of HH 137, almost coincident with a high-density molecular clump detected in the CO(3-2) line and in the cold dust emission at 870 m. We derive the main physical parameters of the molecular clump and the molecular outflow linked to the central protostellar source, and propose a simple scenario for the whole complex
