The Tatacoa Desert is the second largest arid zone in Colombia after the Guajira Peninsula. It occupies 330 square kilometers of land. This semiarid region is located north of Huila Department, 38 km from the city of Neiva in Colombia and 15 km (9 mi) from Natagaima in Tolima. It is a rich deposit of fossils and is a great tourist destination. The Tatacoa Desert has two distinctive colors: ocher in the area of Cuzco and gray in the Los Hoyos area.
The Tatacoa, or the Valley of Sorrows, as it was called in 1538 by the conquistador Gonzalo Jiménez de Quesada, is not just a desert, but a tropical dry forest. The name "Tatacoa" also given by the Spanish, refers to rattlesnakes. During the Tertiary Period, it was wetter, with thousands of flowers and trees, but has been gradually drying up to become a desert.
The Tatacoa covers 330 square kilometers around the city of Villavieja. The area is heavily eroded and crossed by dry canyons that develop transiently in the winter months. These shapes are created on clay surfaces, creating labyrinthine gullies in the landscape that can reach 20 meters deep.
Fauna and flora
There is relatively little runoff, and animal and plant life is adapted to the conditions of low humidity and high temperatures. The plants in this area are adapted to climatic conditions through the development of horizontal roots of up to 30 meters and vertical roots upt o 15 meters deep that facilitate access to water. Wildlife includes turtles, rodents, snakes, spiders, scorpions, eagles, alligators and wildcats, and cacti reaching between four and five meters high.
In addition to its geography, its atmospheric conditions are good for astronomy. Tatacoa has little pollution or noise, attracting tourists who stay there to enjoy the silence, scenery and tranquility.
