Villalba and the southern foothills of the central cordillera define the landscape of this 2024 survey, where the Río Toa Vaca and Río Descalabrado drain southward toward the Caribbean coast. The map illustrates a complex network of island routes, including Carr 150 and PR-14, which connect rural settlements such as Palma Sola, Zanja Blanca, and Río Cañas. The southern portion of the quadrangle shows a shift toward more concentrated infrastructure, including the Universidad Ana G. Méndez Centro Universitario de Santa Isabel and the NG FT Allen RQ 177 military reservation. Topographic landmarks like Cerro de las Cuevas and Cerro del Muerto rise above the valleys, marking a terrain where modern academic and military facilities sit alongside traditional agricultural communities like Paso Seco and Las Ollas.
