Central Roig anchors the northern coastal plain of this 1947 survey, representing the industrial heart of the region's sugar economy. The landscape is defined by the contrast between the flat Valle de Yabucoa, crisscrossed by irrigation and drainage features like the Caño de Santiago and Zanja, and the steep ascent into the Cuchilla de Panduras. This range dominates the southern half of the sheet, rising toward Cerro Santa Elena and creating a natural barrier between the municipalities of Yabucoa and Maunabo. Along the Mar Caribe, the coastline is marked by prominent points including Pta Quebrada Honda and Pta Yeguas, while a Pyramid Beacon near Puerto Yabucoa indicates the importance of maritime navigation for this coastal agricultural hub.
