Malpaís de Güímar
Malpaís de Güímar or Badlands of Guimar consist of a volcanic cone, subsidiary cones, and several basaltic lava flows in the Güímar municipality on the island of Tenerife, in the Canary Islands, (Spain). They total in area about 290 hectares. The lava flows are quite recent, less than 10,000 years old of the typical aā type. The large cone is called ''Montaña Grande'' (''Big Mountain'') and reaches a height of .
==Geography==
The Malpaís de Güímar were formed by a series of volcanic eruptions, the most recent and most evident occurring from fissures in the side of the Montaña Grande cone less than 10,000 years ago. However, two peaks from former eruptions stand above the lave plain, ''Montaña de la Mar'' (''Mountain of the Sea'') and ''Las Morras del Corcho'' (''Cork Bluff''). In addition to aa lava flows, there have been pyroclastic eruptions of ash and volcanic bombs that actually formed the various cones. The crater of Montaña Grande is about 300 meters in diameter and about 50 meters deep. It also has a certain asymmetry, being wider towards leeward due to the action of the wind during its period of formation. The shore line has eroded back since the last eruptions and beaches have formed in a few areas. In places lava tubes have been exposed. Notable is ''Cueva Honda'' (''Deep Cave'') which was formed by a large gas bubble within a lave tube.
