The Patagonian Desert is located in southern Argentina, South America, to the east of the Andes Mountains, with an area of approximately 673,000 square kilometers. Patagonia generally refers to the region east of the Andes Mountains in South America, south of the Colorado River, mainly within the territory of Argentina, with a small part belonging to Chile.

The terrain of the Patagonia region mainly consists of plateaus and narrow coastal plains. Rivers originate from the Andes Mountains, flow eastward into the Atlantic Ocean, cutting through river valleys. However, due to the low rainfall in the area, most rivers are intermittent. The southern part features many glacial formations, such as fjords. Influenced by the Falkland Current, the climate in Patagonia is cold and dry, with an annual average rainfall between 90-450 millimeters and an annual average temperature ranging from 20°C to 60°C. The further south you go, the colder and drier it gets. The eastern part of Patagonia is mainly desert and semi-desert plateaus, sloping in a step-like manner from west to east. Towards the east, there are steep cliffs leading directly to the Atlantic Ocean. Due to ancient glaciers and modern arid climates, the surface features ice-eroded valleys, glacial moraines, proglacial lakes, and various wind-eroded and wind-deposited landforms.
