A Phonolitic Dyke in Mount Teide National Park
This rather phallic feature is one of the many phonolitic dykes that rise above the plain of Las Canadas in the caldera of the Mount Teide Volcanic Complex. The dykes were intruded vertically through cracks in the bedrock and being harder than the originally rock have been more resistant to erosion. Similar Phonoliic rocks form the beautiful Bass Rock Island and world-class bird sanctuary, just off East Lothian, in Scotland.
