Description


Etymology of the name

The name, (Guadarrama Mountains), is taken from the Guadarrama River and the town of
Guadarrama Guadarrama is a town and municipality in the Cuenca del Guadarrama comarca, in the Community of Madrid, Spain. Its population is 13,032 (winter, according to a 2006 census); the population swells to approximately 60,000 in summer. Its name co ...

words for 'sandy river' — composed of ''guad'' (from , meaning 'river') and ''arrama'' (from , meaning 'sandy'). Another interpretation considers unlikely that a minor river could design a vast mountain range, and makes the name derive from the Latin , meaning 'water divide', which very aptly describes the position of the sierra between the two largest water basins in the

It is located entirely within the Community of Madrid, between the Cuerda Larga and the main alignment of the mountain system, running in a southwest to northeast direction, and located, with respect the range as a whole, at its northeast stretch. The valley is more than 25 km in length and 6 km in average width. The slopes of the valley are covered with wild pine, oak and chestnut forests. By contrast, the lower valley area is dominated by grass pastures and farm crops. In the heart of the valley are two towns: Rascafría and Lozoya, both of which lend their names to the two rivers that run through the valley.

Climate

The Guadarramas have climatic features, characterized by considerable temperatures changes between summer and winter and a very dry summer. But, as in any mountainous zone, the climate on the mountains proper changes markedly with increases in height, and can be differentiated into discrete climatic zones. Between 800m and 1,400m, the average annual temperature varies from 9 °C to 13 °C, with a summer high of 28 °C and winter low of -3 °C. Average annual

is between 500 and 800 mm, predominately in non-summer months. At this elevation, much of the precipitation falls as snow, between December and February, although there are always exceptions, and the snow rarely remains unmelted for more than three days. It is in this region that all cities and the majority of people live; this also means that of all distinguished elevations, it is the most susceptible to damage from human traffic and intrusion. Between 1,400 and 2,000 m, the average annual temperature is 6-9 °C, with a summer high of 25 °C and winter low of -8 °C. Average annual precipitation increases with the height to 700–1,300 mm, again primarily during the non-summer season in the form of snow, but between December and April. Much of the snow remains on the ground for the duration of the winter, especially on the range's north slope. Between 2,000 and 2,428 m, the average annual temperature is between 4-6 °C, with a summer high of 20 °C and a winter low of -12 °C. Average annual precipitation is between 1,200 and 2,500 mm, mostly snowfall between November and May which remains all winter and into the spring. In summary, the climate of the Guadarramas is quite humid, more so than that of the rest of the ''Meseta Central'' (Central Plateau), and generally cold, increasing with elevation. In the peaks the wind is usually very intense and thunderstorms in the mountains are more frequent than in the plateau.

According to local people, for a time, the corpses of the three bandits could be seen in a crack of the rocks.
