Caño Cristales: Difference between revisions

Caño Cristales is a fast-flowing river with many rapids and waterfalls. Small circular pits known as [[giant's kettle]]s can be found in many parts of the riverbed, which have been formed by pebbles or chunks of harder rocks. Once one of these harder rock fragments falls into one of the cavities, it is rotated by the water current and begins to carve at the cavity wall, increasing the dimensions of the pit.

The Serranía de la Macarena is located on the border of three large ecosystems, each of them with high diversity of flora and fauna: the Andes, the Eastern Llanos, and the Amazon rainforest. Plant and animal life are struggling with the lack of nutrients on the solid rock surface of the tableland and have developed diverse adaptations. The representative biome of the Serranía de La Macarena is the hydrophytic rainforest: hot, warm, and cold. The tableland is home to about 420 species of birds, 10 species of amphibians, 43 species of reptiles, and 69 primates.
