(Redirected from Northern Karst) Limestone karst landscape located in the northern part of Puerto Rico
Mogotes in the Northern Karst of Puerto Rico.

The Northern Karst Belt (Spanish: Cinturón del Carso Norteño) is a limestone karst landscape located in the northwestern region of Puerto Rico. A karst is a topographical zone formed by the dissolution of soluble porous rocks, such as limestone, with features such as mogotes, canyons, caves, sinkholes, streams and rivers, all of which are common on this region of the island. Some of the island's main rivers, including its longest (La Plata River), traverse the karst and form some of the most distinctive Puerto Rican geographical features such as the Camuy caverns. Many of these rivers feed into and are important in the formation of many marshy areas such as the Caño Tiburones wetlands.

Notable features

Mogotes

A mogote (English: /məˈɡoʊti/, Spanish: /moˈgote/) is an isolated hill with steep, almost vertical, walls that are completely or partially surrounded by alluvial plains. These hills are a characteristic feature of northern Puerto Rico and they can be seen along the north coast from Aguadilla and Rincón in the west to Canóvanas in the east. The highest mogote in the Northern Karst is Cerro El Sombrero in Isabela, Puerto Rico at 1,069 feet (326 m) of elevation. Some renown mogote areas are the town of Florida, located on an alluvial valley completely surrounded by them, and the Arecibo Telescope which was built into a natural sinkhole surrounded by mogotes in Arecibo. The San Patricio State Forest is partially located on the Mogote de San Patricio in San Juan and mogotes can also be seen at the Julio Enrique Monagas Park in Bayamon.

Arecibo Valley

The Arecibo River flows through a wide alluvial canyon called the Arecibo Valley (Spanish: Valle de Arecibo). Highway PR-10 runs from north to south parallelly to the canyon and it provides access to Cueva Ventana, a cave located on one of its cliffs. Many important tributaries of the Arecibo River, such as the Tanamá and Caonillas Rivers, flow into the canyon. Dos Bocas Lake is a reservoir located in the southern edge of the valley. The Río Abajo State Forest is located nearby.

Camuy Canyon and Caverns

Main article: Parque Nacional de las Cavernas del Río Camuy

The Camuy Canyon (Spanish: Cañón del Río Camuy) is formed by the Camuy River, which flows from the cave system of the same name in the south. The canyon also constitutes the border between the municipalities of Camuy and Hatillo. Other caves in the area are Cueva Espiral and Cueva Catedral. The Tres Pueblos sinkhole is also located nearby.

Guajataca Valley

The Guajataca River flows into the Atlantic passing through a canyon called the Guajataca Valley (Spanish: Valle de Guajataca), between the municipalities of Isabela and Quebradillas. The Guajataca State Forest is located along the western edge of the valley.

Ecology

The karst region of Puerto Rico holds the most extensive forest canopy cover on the island due to its rugged topography; the Northern Karst is considered of high potential for recovery of endangered species, including the Puerto Rican parrot (Amazona vittata). This area has the highest biodiversity in the island with 1,300 species of plants and animals, including 30 federally listed threatened and endangered species.
