Bosque Insular de Guilarte dominates this high-altitude landscape along the Cordillera Central, where the steep drainage of the southern slopes is harnessed for power. The 1940s infrastructure is centered on the Salto Garzas Planta Hidroelectrica No 1 and Planta Hidroelectrica No 2, illustrating the era's focus on hydroelectric development in the island's interior. Scattered mountain settlements like Mata de Plátano and Rucio are connected by a network of winding roads and trails that follow the complex ridgelines. The map clearly defines the high-country boundary between the Municipio de Adjuntas and Municipio de Peñuelas, tracing the divide where the headwaters of the Río Guayanés and Río Tallaboa begin their descent toward the coast.
