In New Granada, the main chain also separates itself into parallel ridges, three of which exist between 2° 30ʹ and 5° 15ʹ of north latitude. The eastern ridge divides the great river Magdalena from the plains of the Meta; none of its summits are covered with snow. The central ridge separates the Magdalena from the Rio Cauca; this is the most lofty of the three, and its most elevated peaks enter the region of eternal frost; the three highest are named _Quindiu_, _Baragan_, and _Guanacas_. The western ridge separates the Rio Cauca from the province of Choco; it attains scarcely 4500 feet in altitude, and nearly loses itself in the province of Darien. These three ridges unite in the district of Pastos in Popayan, and continue single till they have far past the equator; when they again separate themselves into two parallel chains, in the province of Quito, by a valley near their summits. It is here that they are seen in their most sublime forms, _Chimborazo_, _Pichincha_, _Illinissa_, _Antisana_, and _Cotopaxi_ ascending to the very skies, their white cones being beautifully contrasted with the dark blue of the surrounding firmament. The second branch of the Andes, called the _Cordillera of the Cataracts of the Orinoco_ extends itself from the great chain eastward between the 3d and 6th degrees of north latitude, where the high plains of Tuquillo and St. Martin, with the peaks of Canavami and Umama are formed; it contains the sources of the Guaviari, the Meta, Zama, and Ymerida rivers, and forms the tremendous cataracts of Maypuré and Aturé; beyond these it acquires still greater elevation, and occupies an immense space, stretching southward to the boundaries of the Portuguese dominions, where it is lost in vast and nearly impenetrable tracts of woody country, over which no European ever trod, as the tribes who inhabit the region are of a ferocious and sanguinary disposition. In this gloomy country exist the sources of the magnificent Orinoco, which have never been seen, either by the civilised Indians, or the Spaniards. The chain has again been observed issuing from forests farther to the eastward; it is, however, neither so elevated nor so broad, and is called _Sierra de Quineropaca_ and _Pacaraimo_, near the lake of Parimé and the Amazons. It again extends its breadth a few degrees further east, and bends southwards along the Mao, where the hill of Ucucuamo, which being formed of shining yellow mica, deceived the venturous travellers, who fancied they at last found a mountain of gold. From this hill, called El Dorado, or the Golden Mountain, the branch stretches eastwards towards the mountains of French Guiana, where its form is little known, as the interior of that country is inhabited by Caribs and negroes, who keep the settlers at bay. The rivers of Berbice, Surinam, Marony, and Essequibo rise in this part of the chain.
