1958 Map of El Yunque

About this map

The high peaks of the Sierra de Luquillo dominate this 1950s terrain study, where the lush rainforest meets the coastal lowlands of Rio Grande. The landscape is defined by the massive presence of El Yunque, Mte Britton, and El Toro (Southwest Peak), forming a hydrological hub where headwaters like the Rio Espiritu Santo and Rio Mameyes begin their descent. Cultural features are concentrated along the northern roads, including the Mameyes (Palmer PO) settlement and the specialized Escuela Segunda Unidad Casiano Cepeda. Historically significant markers of the era include the Area de Recreo La Mina and the nearby Mina, reflecting the dual use of the mountain as both a recreation destination and a site of former industrial interest. This map captures a moment when the Estacion Guardabosque and various youth camps like Campamento Eliza Colberg were integral to the area's forest management and social fabric.
