Montes Universales is a 32 km (20 mi) long mountain range in the southeastern end of the Iberian System. Its highest point is the 1,935 m high summit known as Caimodorro. The 1,830 m high Muela de San Juan is another important peak.
The range, which is aligned in a NW - SE direction, is not as high as neighboring ranges. It is, however, very significant from the hydrographic point of view, for important rivers of the Iberian Peninsula have their source in these mountains, which divide the Atlantic from the Mediterraneanwatershed. Among the Iberian rivers that originate in the Montes Universales, the most important are the Tagus on the western slopes, and the Túria, Cabriel and Xúquer on the eastern.
These mountains are covered with, mostly not very dense, clumps of pine, oak and Iberian juniper forest.
Radiocarbon samples from Ojos del Tremedal show that birches, now almost absent from these mountains, were very common in the Montes Universales during the ice age around 9,600 years ago. Signs of human interference with the vegetation have been detected beginning about 3,500 years Before Present.[2]
