The processes of settlement and colonization in the middle basin of geographic Cauca valley, from the eighteenth century to the late nineteenth century, account for several phenomena that must be dealt historiography to develop hypotheses associated with types of border, as the Cimarron typology that some way can be interpreted as features of hegemonies communal settings and therefore challenged approaches that give a totalizing colonization of Antioquia character. The forgetfulness and silence on the cultural, social, economic and symbolic background of Cimarron border which were part Sopinga and much later Canaveral del Carmen, at the confluence of the rivers Cauca and Risaralda, are themselves the central problem of our historical research and reflection in order to establish the effects that corporate colonization occurred that gave rise to an agricultural export border claims of civilizing and modernizing the territory. The explanatory model adopted for the study of this phenomenon was based on analyzing the types of colonization and border in the valley of Risaralda, and particularly welcome the thesis-border refuge, from which it is possible not only to test the concept of border setting, but to interpret the configuration of a Cimarron border through the establishment of Palenques along the Magdalena and Cauca rivers, as observed in this work. The official history of the valley of Risaralda is contained in novels and stories as a result of the cultural products of the business frontier. Hence its analysis in light of the use of primary sources and theoretical concepts welcomed, allowed to appropriate reflection problem associated with forgetfulness, silence, denial and concealment of a narrative own that, somehow or other, to ingratiate himself with the voices of the victors.
