As part of a multi-frequency study of southern hemisphere jets and molecular outflows being carried out with Gemini and APEX, in this contribution, we present a detailed analysis of HH 137 and HH 138. Several 2.12 micron knots linked to HH 137 are identified in the Gemini image, as well as in Spitzer images. 12^CO(3-2), 13^CO(3-2), and C18^O(3-2) line data reveal the molecular counter-part 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 C18^O. We derive the main physical parameters of the molecular clump and the molecular outflow, and propose a simple scenario for the whole complex.
