Cordillera Central defines the spine of this Puerto Rican interior, where the high mountain ridges serve as natural barriers and jurisdictional markers between the municipalities of Orocovis, Coamo, and Villalba. Topography recorded in 1943 reveals a complex landscape of steep ravines and prominent peaks like Cerro El Malo, where small mountain trails and homesites are perched high above the watershed. The drainage patterns are particularly intricate, with the Rio Bauta flowing northward while southern systems like Rio Toa Vaca and Rio Coamo carve deep paths through the Cuchilla de Coamo. This preliminary study shows the rural character of the central highlands before major modern infrastructure, focusing on the natural contours and the scattered homesteads that followed the ridges and creek beds of Quebrada Hayales and Rio Descalabrado.
