We present an analysis of YSOs linked to the IR dust bubble complexS21-S22-S23-S24 of about 12 arcmin in size, which also includes infrareddark clouds and EGOS. The study reveals the presence of many YSOs andtheir correlation with molecular gas (CO data from APEX) and dust. TheYSOs identified in IR point source catalogs indicate that the complex isa very active star forming region with sources in different evolutionarystates. Outflow signatures is also investigated. We compare the mainparameters of the different sections of the complex in order tocharacterize the star forming process
