Los Roques de Garcia

Los Roques de Garcia

Los Roques de Garcia lie across the middle of the Las Canadas caldera beneath Teide in Tenerife. They are the remains of the plumbing system inside a huge stratovolcano that erupted in a violent Plinian eruption, associated with a landslide to the north of the island. In a relatively relaxing two and a half mile circular walk, you can capture breathtaking views of Mount Teide, pyroclastic rocks, the famous Roque Cinchado, a lava fall, cone sheets, columnar jointing, pahoehoe lava, a volcanic plug and also walk on the caldera floor. Take a look at the map, take in the surroundings using Street View, click on the markers to find out more or browse photographs from the whole walk.

Tenerife Street View

Google Street View in Tenerife

Google's Street View car has been all over Tenerife, including the road through Mount Teide National Park, the whole of which is worth exploring. But there are lots of other places that are worth looking at in Google maps.

Click on the links below. When the placemarkers have opened, select more and go to Street View to see some amazing views and fascinating locations.


The cliffs at Los Gigantes - the highest cliffs in Europe.
The coast at Garachico - a town inundated with lava in 1706.
The bridge over Barranco de la Orchilla - a deep gorge in the south of the island.
Caves for workers at Chimiche quarry - carved out of the local pumice.
The bridge at La Cisnera - how does it stay there?
A lava tube in the Corona Forestal - once filled with molten lava, now an empty tube.
The road cutting near Montana de la Negra - black and white layers from Plinian and Strombolian eruptions.
The view of Teide across the caldera floor - just one sample of the views across the caldera.

Tenerife geology 2009 day 2

Tenerife geology fieldwork December 2009 - Day 2

The second day of the December 2009 trip was the section from San Miguel de Abona to Cisnera. The rocks are mainly phonolitic, with evidence of Strombolian and major Plinian eruptions, including a scoria cone with volcanic bombs, lava flows, a lava dome, pumice fall, pyroclastic flow and block and ash flow deposits. The photographs can be found on Picasa and the map for the day on Google Maps. Both can be found from links on my Google site.

Tenerife geology 2009 day 1

Tenerife geology fieldwork

For the last three years, I have visited Tenerife with groups of A'level geology students, staying in Playa de las Americas and Los Gigantes. We have visited sites close to the south, centre and western end of the island. In 2009, I carried a Garmin GPS and produced a map of the trip. This evening, I have finally finished attaching the photographs from the first day, when we visited Los Gigantes, Santiago del Teide, Masca and Garachico. The photos from 2009 are a more manageable collection than the gigabytes that I have taken subsequently. I have added a comment to each photo explaining why I think it is significant. As I finish the rest of the database, I will publish the links at https://sites.google.com/site/carpebble/home/geology.

Scorrier chapel GigaPan

GigaPan Panorama of Scorrier Chapel front lawn

I took the photographs last Friday evening and stitched them using Hugin. Scorrier Chapel is a former methodist chapel and the home of Scorrier Christian Fellowship. The building has a striking stone facade, consisting of dressed granite and killas, both quarried locally. Opposite the chapel is the Crossroads Motel. The main train line from Penzance to Plymouth can be seen to the left of the photograph.
