“ Huge bridges span the ravines, though for more than half the year not a drop of water passes over their pebbly beds.
The Sierra de Guadarrama and its western continuation, the Sierra de Gredos, separate this central plateau of Spain into two portions, lying at different elevations. Old Castile and Leon, which lie to the north, in the basin of the Duero, slope down from east to west from 5,600 to 2,300 feet; whilst New Castile and La Mancha, in the twin basins of the Tajo and the Guadiana, have an average elevation of only 2,000 feet.

“ The winter here, especially in the elevated region of the Paramera and the waste lands of Ávila, is long and severe, but the climate is not unhealthy. In this region stock-breeding is an important industry. The principal mountain chains are the Guadarrama, separating this province from Madrid; the Paramera and Sierra de Ávila, west of the Guadarrama; and the vast wall of the Sierra de Gredos along the southern frontier, where its outstanding peaks rise to 6000 or even 8000 ft. ”

“ These sheets of fresh-water covered the centre of the country, including the basins of the Ebro, Júcar, Guadalaviar, Guadalquivir and Tagus. They have left behind them thick deposits of clays, marls, gypsum and limestone, in which numerous remains of the land-animals of the time have been preserved.
Quaternary deposits spread over about a tenth of the area of the country. The largest tract of them is to be seen to the south of the Cantabrian chain; but another, of hardly inferior extent, flanks the Sierra de Guadarrama, and spreads out over the great plain from Madrid to Cáceres.
