Desembarco del Granma National Park: A Geological Treasure of Cuba
Located on the western edge of the Sierra Maestra range, Desembarco del Granma National Park is a site of immense geological significance. Situated along the tectonically active boundary where the North American Plate meets the Caribbean Plate, the park serves as a living record of the Earth's shifting crust and changing climates.
The Majesty of Limestone Terraces
The park is most renowned for its series of limestone terraces, which are considered among the largest and best-preserved in the world. These formations span a dramatic elevation range, stretching from 180 meters below sea level to 360 meters above.
These terraces were created through a combination of tectonic uplift—the vertical elevation of the Earth's surface due to plate movements—and fluctuations in sea levels. These changes were driven by past climate shifts and glaciation events occurring during the Miocene, Pliocene, and Pleistocene epochs.
[ไม่มีภาพประกอบ]Diverse Karst Landscapes
Beyond the terraces, the park protects a variety of karst features. Karst refers to landscapes formed from the dissolution of soluble rocks, such as limestone, which creates unique topographical structures. Visitors and researchers can find a wealth of these features throughout the park, including:
- Dramatic cliffs and deep sinkholes.
- Intricate cave systems.
- Scenic waterfalls.
Climate and Environment
Desembarco del Granma National Park is characterized by a warm, semi-arid climate. It is one of the warmest and driest regions in Cuba, with an average temperature of 26°C. Annual precipitation varies significantly, ranging between 300 and 1200 mm of rain.
