The town of Ciales sits as a central hub on the north-central slopes of the Island of Puerto Rico, where the landscape is defined by the deep carving of the Río Grande de Manatí and its numerous tributaries. This survey captures the intricate relationship between human settlement and the complex hydrography of the region, where roads like PR 149 must navigate between steep elevations and winding stream beds. To the east, the municipality of Morovis is anchored among the hills, while the southern reaches of the quadrangle rise toward significant peaks such as Cerro Avispa and Cerro Cedro. Genealogists and local historians will find the Cementerio de Ciales clearly marked near the town center. The map documents a rugged interior geography where nearly every valley is named, from Quebrada Ventana to Quebrada del Pozo de Magala, illustrating a deeply established rural naming tradition that persists alongside modern infrastructure.
