Rivera Department
There are three chains of low and rounded hills in the department. These chains of are known as cuchillas in the country. At the northwest end of the department is the Cuchilla de Haedo, one of the most important cuchilla of the country, coming from the south; it meets the Cuchilla Negra that comes from the north. Between these two hill ranges is the Cerro de los Peludos hill. Along the borders with Brazil, to the north, runs the Cuchilla de Santa Ana.
