Mountains occupy a strategic place in the political ecology of the war in Colombia. The mountains have been converted into places for military operations, and territorial disputes have become the most important discursive and actual scenario in the so-called guerrilla war that has taken place in the country for more than 40 years. One particular discursive construction related to the mountains in the context of war is the category of “refugee place” for armed groups associated with illicit drug production. For many people the mountains are “dangerous territory.” For rural inhabitants of the mountains, life takes place between conflicts. The present essay presents a brief analysis of how mountains are defined by categories and actions in one scenario involving the armed forces. It argues that social representation of mountains in the context of war overlaps with discourse established in anthropology about categories of culture and nature. It presents a point of view based on discourse and social representation of mountains that is becoming crucial for understanding the ways in which territories are controlled and these territories are perceived by local culture.
