El Cocuy National Park is a park in the Andes Mountains of Colombia. Its official name is Parque Nacional Natural El Cocuy.
Geology
El Cocuy is located near the equator but has a very high elevation. Because of this, the area has geological features shaped by glaciers, such as steep slopes, bowl-shaped valleys, rock piles left by glaciers, and lakes carved by glaciers, including La Pintada and La Cuadrada. The park's elevation ranges from 4,500 meters (15,000 feet) at its lowest point to its highest point. The park is visited by climbers and rock climbers of all skill levels.
Geography
El Cocuy National Park is in the Department of Boyacá, close to the villages of El Cocuy and Güicán.
Hydrography
El Cocuy National Park is important for controlling water in the region, as it is the source of many water bodies that flow from its interior into three large river systems: the Arauca River (with rivers like Cusay and Cabugón), the Casanare River (including rivers like Nevado and Tame), and the Chicamocha River subzone (with rivers like Playitas and Orozco). This water system provides water to towns and villages in the departments of Boyacá, Arauca, and Casanare. In addition, the park helps regulate the climate by absorbing carbon dioxide from the air, thanks to its páramo and Andean forest ecosystems, which reduces the effects of climate change. Its ability to collect, store, and release water, along with its influence on temperature and humidity, makes the park a key part of the environment, helping to keep the area healthy and sustainable.
Climate
The climate of El Cocuy National Park changes a lot because of its wide range in elevation, which goes from 600 meters (1,968.5 feet) to 5,330 meters (17,487 feet) above sea level. This range creates many small areas with different weather, called microclimates. Temperatures in these areas can range from as low as -4°C (24.8°F) at the highest points to as high as 24°C (75.2°F) at the lowest points. At the highest mountain areas, the climate is cold and dry, with occasional snow, strong sunlight, and frequent fog. Rainfall is moderate and happens during both dry and wet seasons, which are common in the Andean region. These weather conditions affect how ecosystems are spread out, from cold highlands to warmer forests near the base of the mountains.
Current events
The park's history with glaciers has made climate change an important factor in its future. A painting from 1851 titled "Great Snowfields near Güicán" shows Mount Chita completely covered in snow. By 2009, the park's historic icefield had become smaller, reduced to small snow patches, and is predicted to completely disappear in a few decades.
