The mountain region in which Montemorelos is today is called the Great Chichimeca. The main nucleus of the municipality was formerly called Villa de San Mateo del Pilón. In the area archaeological works have been carried out since 1960 by Jeremiah Epstein and more recently by Moisés Valdés Moreno and Araceli Rivera. Few archaeological elements have been found: some mortars, jars, stoves, petroglyphs or cave paintings, botanical remains of animals, arrowheads, scrapers, etc. An important finding is that of the remains of a mammoth, arrowheads and hearths in 1996. It is difficult to determine which ethnic groups inhabited the Pilón Valley before the arrival of the Spaniards. Like all of northern Mexico, called chichimecas in general, they were nomadic and did not usually have large settlements.
