Cuchilla Grande
The Cuchilla Grande (in German: sharp comb or edge of a knife) is the most important range of hills in Uruguay with up to 513 meters .
The Cuchilla Grande range of hills enters the country from the north as a continuation of the Serra Geral from Brazil and runs through the same in the south-west to about 34 ° south-east latitude. It dominates the south-eastern part of the country and extends to the southern Atlantic coast near Maldonado . The highest points of the hilly landscape can be found in the north on the border with Brazil. Further inland, the Cuchillas sink more and more and mostly appear as undulating hills or low ridge-shaped rock ranges. In the far south, the narrow range of hills of the Sierra Carapé connects directly to the east , in which the Cerro Catedral is the highest point in Uruguay. Here the appearance is more mountainous again and the elevations reach almost the same heights as in the border area with Brazil.
The Cuchilla Grande forms a watershed with its southwestern branches , as it separates the basin of the largest river, the Rio Negro , from the rivers that flow into the Atlantic Ocean. Many rivers have their source here, such as the Río Olimar , the Río Olimar Chico , the Río Yí , the Río Tacuarí , the Arroyo Chuy del Tacuarí , the Arroyo Canelón Grande , the Arroyo Fraile Muerto , the Arroyo Solís Chico , the Arroyo Yerbal Grande or the Arroyo de Godoy .
