Maddela
Maddela lies in the upper Cagayan basin of northern Luzon, where the river passes the foothills of the Sierra Madre. The forests and valleys were home to Ilongot and Dumagat communities, who hunted in the hills and fished along the river. In the eighteenth century Agta people occupied lands east of the Cagayan toward the Pacific, moving through a landscape of wooded ridges and waterways. The river provided a path through this rugged interior.
