Croscat
The ''Croscat'' ((:kruskat)) is a volcano in the comarca of Garrotxa, Catalonia, Spain. It is both the youngest and highest volcano in the Iberian Peninsula, with the last eruption dated back to about 14,000 years Before Present. The volcanic cone has a horseshoe shape and its northeastern flank was quarried for volcanic gravel until the early 1990s, exposing the internal structure of the cone from top to bottom. The volcano is located in the Garrotxa volcanic field, a Quaternary volcanic field also known as Olot volcanic field, as part of the protected area of the Garrotxa Volcanic Zone Natural Park.〔〔
==Geology==
The cone has a height of 〔 and an elliptical base with a horseshoe shape, probably caused by the breaching of the western-side of the volcano as a result of the effusion of lava flows during the last eruptive phase of Croscat.
A study published in 2011 at the Journal of Volcanology and Geothermal Research revealed that the Santa Margarida Volcano and the Croscat were the product of the same eruption event 11,500 years ago, alternating phreatomagmatic activity, between water and magma, and magmatic activity.〔〔
