Geologists in Gran Canaria
As I mentioned at the end of my previous post, Gran Canaria to me was a sort of eye opener to a different world. A world of constant warm climate, sunshine, beaches, palm trees and luxury tourist resorts. A sort of idealized island paradise world, where, at least in the moment, one doesn’t care about money anymore. That’s because presumably one already has enough money if they end up in a place like this.
Well I didn’t have money… But I felt like I did. This feeling is what I mean by I got a small taste of “the good life”. Something I’d never felt before. I relished the feeling and wanted more. My experience in Gran Canaria ignited an ambition for success that would shape some of the most momentous decisions later on in my life.
But I’m getting ahead of myself now. Let me first tell you about our adventures on the island.
Road trips across a volcanic island
We spent most of our days in Gran Canaria on the road. Driving around and across the island to observe its magnificent geological features.
Like the rest of the Canary Islands, Gran Canaria is a volcanic island made up of various volcanic rocks ranging from basalts to rhyolites. This range of rock types from silica-poor to silica-rich represents the typical evolution of ocean island forming magmas.
Another typical rock type in Gran Canaria are ignimbrites. Ignimbrites are basically hardened volcanic tuff formed as a result of pyroclastic flows. For those unaware, pyroclastic flows are those superheated “grey avalanches” of gas and volcanic particles moving down the slopes of an angry erupting volcano at very high speeds. They are probably the most dangerous features of a violent volcanic eruption. Their direction is very hard to predict, you can’t outrun them and they incinerate and carbonize everything in their path.
In the end, all that violent rocky and gassy outburst, coupled with erosion leads to some really unique rock formations.
Fuente de los Azulejos
The name of this colorful geological formation literally translates to the fountain of tiles. Located in the municipality of Tejeda in the center of the island, los Azulejos are a result of hydrothermal activity and oxidation, coupled with erosional features.
The rocks at los Azulejos are primarily composed of basalts. The green and blue colors come from an abundance of copper minerals such as malachite and azurite. Water and erosion over time contributed to the distribution of these colors across a large area.
Roque Nublo
Another geological feature and major tourist attraction in the municipality of Tejada is Roque Nublo. Translated to “Rock in Clouds” this 80 meter high rocky monolith towers over the surrounding landscape.
One of the most iconic landmarks of the island, Roque Nublo offers spectacular panoramic views of the rolling hills and valleys of the Gran Canaria. On top of that, you get a spectacular view of Tenerife island in the distance.
Initially a landscape made up of various lava flows, ash and pumice, was shaped over millions of years by wind and water. In time, erosional forces have erased all but the most resilient of rocks which today make up the core of Roque Nublo.
Dragon Tail cliffs at Mirador del Balcón
Located on the western coast of Gran Canaria, the Dragon Tail Cliffs at Mirador del Balcón are geological formation renowned for their dramatic appearance and panoramic views. The epic name was derived from the jagged, serrated edges of the cliffs, which resemble the tail of a dragon in silhouette against the sky.
The cliffs at Mirador del Balcón are composed of basaltic lava flows, which in time have been carved and sculpted by winds and waves. The dramatic shapes of these cliffs are a result of the high durability and resistance to erosion of basaltic rocks.
Bandama Caldera
Measuring approximately 1000 meters in diameter and 200 meters deep, the Bandama Caldera is one of the Canary Islands largest volcanic craters. Located near the town of Santa Brígida, the caldera offers yet more stunning views and geological features.
The Bandama Caldera is the result of a massive volcanic eruption that occurred thousands of years ago. The subsequent collapse and erosion of the caldera left a large depression in the landscape.
On the road from the Bandama Caldera towards the coast you can find some of best examples of pillow basalts. These structures form during underwater lava eruptions, as a result of rapid cooling.
Mapping ignimbrites
On one of the days we split into multiple teams and did a field study of different rock formations. My hotel roommates and I were assigned to map ignimbrites. As such, Nigel, Søren, Michael and I spent one day in the scorching sun noting down the features of this huge wall of rock along a sloped road.
Below us, in the valley, there was a raging pool party at one of the resorts. Not having an ounce of shade the whole day, we became quite disgruntled with and jealous of the people below. They were also playing that damned “Tunak Tunak” song on loop the whole day… To this day I can’t stand listening to that song because of this!
Despite our complaints, we still had a great time doing fun geology things while sometimes stopping to admire the views of that incredible place. Later on we would compile a report of our findings, which would contribute towards the final grade of the course.
Leisurely evenings
After our daily road trips, sight seeing and geology work, we would spend our late afternoons and evenings doing various activities. Be it a dip in the pool, a walk across town, or a night of drinking on the terrace, there was always something to do.
One of my favorite nights was poker night with my roommates. Søren had brought a poker set with him, so the four of us sat down for a very serious game of Texas Hold’Em. The stakes were high as we were playing for drinks. Losers buy the winners one and two beers respectively. After a crafty combination of luck, aggression and bluffing, I had managed to secure my second place and one free beer. However, my luck was up as the most inexperienced of us actually managed to win the big pot! Regardless, I was quite pleased with my results.
During the last evening, Paul Martin took us all out for a game of mini golf. This was after we had a few drinks. Among them a couple of shots of true Absinth. The 89.9% alcohol drink that gives you brain damage. To my surprise it tasted better than some other dreadful things I drank in my life – hint hint, Swedish bitter and Stroh rum… Ugh…
On top of all this we had an incredible varied buffet dinner each night. I will never forget the seafood themed one. Just the variety and the taste of it all was so good! Suffice to say the nights were a blast.
Final thoughts on our trip
As a holiday trip and adventure, Gran Canaria is up there on my list with some of my most memorable trips. However, as part of a university field course? Hands down the best course I’ve ever taken!
Field courses are always more fun than just sitting in the class, or lab all day. I’ve done quite a few back in Romania during my Bachelors days. But of course the level of financing and opportunity between my Romanian and Danish Universities was incomparable.
I mentioned how my trip to Gran Canaria turned on an ambition switch in my head that would pave the way for future decisions and successes. However, there was another thing I gained from my field trip there. An immense gratitude and respect towards my professor, Paul Martin, the University of Copenhagen and Denmark in general. So much so that when we flew back to Denmark I decided that I would sign up for the state offered Danish language classes and I would try to make Denmark my permanent home.
