Mante
The Mante River rises near the eastern flank of the Sierra Madre Oriental and joins the Guayalejo basin in southern Tamaulipas. Springs, streams and wetlands mark a transition between the mountains and the lowlands. Huastec communities inhabited this region before Spanish colonization, with settlements in the valleys and the neighbouring Sierra de Cucharas. The river’s waters supported a landscape of marshes and small islands near its lower course.
