Ponce Limestone includes beds of brown clay and has a maximum estimated thickness of 850 meters. [4] It consists mostly of yellowish-orange, soft to moderately hard, fossiliferous limestone and appears almost continuously as a narrow band extending from Bahía Montalva in Patillas to Río Pastillo, in Barrio Canas.
Carboniferous Limestone – Limestone deposited during the Dinantian Epoch of the Carboniferous Period; Coquina – Sedimentary rock that is composed mostly of fragments of shells; Coral rag – Limestone composed of ancient coral reef material; Chalk – Soft carbonate rock; Fossiliferous limestone – Limestone containing fossils
The Parque Nacional de las Cavernas del Río Camuy (English: Camuy River Cave National Park) is a cave system in Puerto Rico. It is located between the municipalities of Camuy, Hatillo, and Lares in northwestern Puerto Rico, but the main entrance to the park is located in Quebrada, Camuy.
Falling Waters State Park lies atop a bed of limestone that has been eroded over the years by water which has created the sinkholes and caverns that are found throughout the park. [10] The waterfalls of Falling Waters State Park fall into a 100-foot (30 m) sinkhole known as Falling Waters Sink. [ 3 ]
The historic zone is located in what is commonly called Ponce Pueblo – the central downtown and oldest area of the city. While there are several roads that lead to it, the most common point of entry is via PR-1, which becomes the Miguel Pou Boulevard, and then into the one-way Isabel Street, leading to the center of Ponce at the Plaza Las Delicias.
The limestone caves in the park have stalagmites, stalactites, and flowstones formed by the erosion of bedrock. Other formations are above ground, including rivers and springs. [1] Florida Caverns State Park and the neighboring golf course were constructed by the Civilian Conservation Corps as part of the New Deal. The park opened in 1942.
A limestone pavement is a natural karst landform consisting of a flat, incised surface of exposed limestone that resembles an artificial pavement. [1] The term is mainly used in the UK and Ireland, where many of these landforms have developed distinctive surface patterning resembling paving blocks. [ 2 ]
The cave is formed in 100-million-year-old Segovia Limestone, of the Edwards Group. The formation of the cave itself probably occurred between 1.5 and 5 million years ago. The cave is formed primarily along joints, which allowed gases to rise up from depths of around 1.5 mi (2.4 km) to then depths of about 300 ft (91 m).
