In page Castile and León:

"

The morphology of Castile and León consists, for the most part, of the northern half of the Meseta Central (Meseta Norte) and a belt of mountainous reliefs. The Meseta Central is a high plateau with an average altitude close to 800 m (2,600 ft) above sea-level; it is covered by deposited clay materials that have given rise to a dry and arid landscape.[citation needed]
