Exploring Akureyri and northern Iceland

Exploring Akureyri and northern Iceland

Following our rocky first day in central Iceland, pun intended, we returned to Akureyri to get our car repaired. With broken rear suspensions, it was a slow and bumpy ride back. All of our stuff was bouncing around for hours in the car. Tools and rock samples collided repeatedly with beer cans, which lead to quite the leaky mess in the back. By the end of the journey, our car smelled like a fraternity dormitory.

On our way back to northern Iceland, Paul took a little detour to show me a gorgeous waterfall spot with columnar basalts. For those who don’t know, columnar basalts are a tall hexagonal rock formations that form when thick lava flows cool and contract. This causes the rocks to crack and break into unique shapes resembling natural stone pillars. Columnar basalts are quite common in Iceland as well as other parts around the world with past or present volcanism.

Several hours later, we arrived in Akureyri and immediately took our car to the mechanic shop. The mechanics soon realized they needed a car part to be flown in from Reykjavik so the soonest they could fix the car was by the next day. Thus, I ended up having a free day to explore Iceland’s biggest northern town.

Akureyri

Often referred to as the capital of northern Iceland, Akureyri is a charming little town nestled at the base of Eyjafjörður, Iceland’s longest fjord. Despite its small size, Akureyri has a good variety of cafes, restaurants and bars along its main street. There’s a beautiful cultural center and botanical garden in the town center as well.

Akureyri was founded in the 9th century by a group of Norse settlers lead by Helgi Magri Eyvindarson. It later gained prominence in the 18th century when Danish merchants established a trading center there. The town’s growth accelerated in the 19th and early 20th centuries, driven by its thriving fishing industry and favorable location in on the fjord, which provided a sheltered harbor for ships.

During World War II, Akureyri served as an important Allied base, contributing to the town’s development and infrastructure. Post-war, Akureyri continued to expand, becoming a cultural and educational hub in northern Iceland.

In modern times, the town has kept its historical charm with well-preserved wooden houses, museums like the Akureyri Museum and Nonni’s House, and landmarks like the Akureyri Church, designed by Iceland’s state architect, Guðjón Samúelsson. This blend of history, culture, and natural beauty makes Akureyri a unique destination in Iceland and one that I’m glad I got to briefly explore.

Northern Iceland

The next morning we eagerly awaited to get our car back from the shop and head out into the field again. Our planned early morning start had to be pushed back as our Landcruiser was still undergoing repairs. The delay wasn’t too bad considering our targets for the day were in northern Iceland, just a few hours drive east. However, Paul was becoming quite impatient. Finally, after a couple of hours, we got the car back, suspensions and all, and quickly drove off towards Gæsafjöll.

Gæsafjöll, northern Iceland

Getting the job done

Gæsafjöll was a relatively obscure hyaloclastite mountain about an hour drive northeast of Akureyri. Just next to it, however, was a much more renowned active volcanic caldera named Krafla. The road took us past Lake Mývatn, a famous tourist attraction in northern Iceland. We then had to take a series of dirt-roads that may, or may not have been private roads.

Different rock layers at Gæsafjöll reflecting different eruptive events

It wasn’t our intention to trespass of course, but the closer we could drive to our mountain, the less time we’d have to waste walking. Finally, we reached a closed gate. So in true explorer fashion we simply let ourselves through. There was nobody around to ask for permission anyway… After getting as close as the road would allow, we parked the car and set off on foot. Within an hour we managed to reach the mountain, sample several outcrops and finish our work in the area.

Collecting my rock samples from Gæsafjöll

It was a beautifully efficient day thus far and we only had one more target to the southeast with plenty of time to spare. When we got back to the car, I noticed cylindrical red piece of plastic in the grass: a shotgun cartridge. It was time to leave.

Still not sure if we were on private property or not, but we didn’t want to stick around to find out

The hunt for Bláfell

Our second and last target for the day was Bláfell, another large hyaloclastite mountain located south of Mývatn. To try to reach it, we’d have to take another one of the F-roads into the Icelandic highlands. But before we’d venture back into the desolate grey lands, we stopped for a nice lunch at a cool little pizzeria on the way!

The perfect lunch stop along the way

After a good meal we hit the road. Trying to figure out the right road once we got off the paved ring road was challenging. We were using what maps we had of the area and our GPS point of where Bláfell should be. We chose to take a road called Grænavatnsgrundir, heading towards Sellandafjall. Bláfell was supposed to be parallel to Sellandafjall and we were hoping the road would curve around the first mountain and get us close to our target.

Our GPS target spot was supposed to be somewhere in those mountains

The all too familiar Icelandic wastelands

Once more we were back in the bleak alien world extending into central Iceland. Apart from some sparse weeds, the vegetation was gone. So was the clear blue sky. As if to mirror the dark desolate rocky wastes, the sky turned a grey overcast.

As the road took us further south, we could glimpse what we thought was Bláfell in the distance to the east. However, it was quite far away with several mountain ridges and a vast terrain of basaltic flows separating us from it. We kept on driving in hopes we’d have the chance to turn towards it at some point. However the further we drove, the more it became clear we were getting further away from our mountain. At that point the road was also just basically a set of old tire tracks we were following.

Driving further south trying to find the end of the massive lava flows to our left

Off-roading had crossed our minds, but considering the extensive wall of lava flows that was flanking us, it seemed quite impossible.

Should we push our luck?

Finally, we reached what looked like the end of the lava flow. However, we were now very far from Bláfell. The road pretty much disappeared by this point. There were still some tire-marks left, but they looked more like dirt-bike or quad tracks rather than car tracks. The only potentially possible way to continue was to cross a fairly steep sand dune and off-road it from there. However, with our previous car troubles and prospects of getting stuck, we weren’t too eager to push our luck. We got out of the car to scout around and our prospects weren’t looking good.

Surrounded by lava flows, our last option to reach Bláfell was going off-road

I was cautiously encouraging Paul to try to brave the sands. As long as we steered clear of the jagged basalts, our car should be fine. However it was also getting late in the afternoon. Considering we had to drive back to Akureyri, we couldn’t afford wasting too much time in the desert. Nor could we afford risking getting lost, or damaging the car again…

Paul weighed our options carefully. Whatever he’d decide, I’d be onboard. With a heavy sigh and a defeated smile, he decided to give up on Bláfell and turn back. The mountain had won this day.

Hverir: a living land of color, heat and gas

On our way back to Akureyri, we made one last stop at Hverir, a geothermal spot near Mývatn. Easily accessible from the ring road, Hverir is a popular tourist attraction in northern Iceland boasting an eerie landscape with vivid colors, bubbling mud pots, hissing steam vents and more.

A surreal landscape of color, heat and gas

The first and probably most striking feature of Hverir is the colorful landscape. Vivid shades of yellow, orange, red, and brown are a stark contrast to the barren surroundings. These colors are due to the high concentration of minerals such as sulfur and iron in the geothermal deposits. Due to the extreme geothermal activity there, the land is also devoid of vegetation.

Mud pots, fumaroles and hot springs

The area is dotted with mud pots, which are essentially pools of hot, bubbling mud formed by geothermal activity. These grayish mud pots are created when the acidic geothermal waters dissolve surrounding rocks into a fine clay, which is then brought to the surface.

Bubbling mud pots at Hverir

Another feature that Hverir is famous for is its fumaroles. Fumaroles are basically steam vents that release sulfurous gases from the Earth’s crust. The steam rises from cracks in the ground, often at high temperatures, and the air is thick with the smell of sulfur, giving the area a characteristic “rotten egg” odor. The corrosive sulfur also creates vivid yellow vuggs in the rocks creating an unsettling dissolution texture.

There were also hot springs in the area, though they were far too hot for bathing. These springs contribute to the steam that rises from the ground, adding to the area’s steamy, surreal atmosphere.

Steaming fumarole at Hverir

The constant flux of heat, steam, and chemicals gradually erodes the surface rocks constantly reshaping the land and the size of its fumarols and mud pots. Due to the extreme temperatures of the ground and steam vents visitors are asked to stay on the marked paths.

I was very happy we got to take some time to go sightseeing at Hverir

After leaving Hverir we drove past several other attractions including the lava fields at Dimmuborgir and the phreatic tephra cone, Hverfjall. I wished that we had more time to explore the wonders of northern Iceland, but for the time being we had to return to Akureyri and prepare for our next field day which would take us back into the heart of central Iceland.

Geologists in Gran Canaria

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.

The landscape of Gran Canaria

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.

The master volcanologist and igneous petrologist himself in action, Paul Martin Holm.

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 colorful rocks of Los Azulejos in Gran Canaria

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.

Hiking towards Roque Nublo we got a view of these clouds rolling over the jagged 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.

The towering 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 Dragon Tail Cliffs at Mirador del Balcón

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.

It was impossible to capture the sheer size of Bandama Caldera in one photo

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.

The perfect pillow basalt

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!

Hearing the Tunak Tunak song for the millionth time

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.

Finishing up a long days work on the rocks

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…

Tasty liquid death

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.

Our geologist version of ‘The shining”

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.

EUGEN: Switzerland 2008

EUGEN: Switzerland 2008

In my previous post I mentioned how I went to EUGEN Switzerland in 2008. I also said I would showcase the field trips I went to during the week there. Now again, because of how long ago this was, I sadly can’t recall the names of any of the places. Perhaps one of my EUGEN friends, Gaudenz, who was one of the organizers for EUGEN 2008, can help out in the comments.

As with each EUGEN event, there were a number of field trips to choose from during our week long stay. Some of them are organized twice, so that people have a chance to do all, or almost all of them. All the field trips are worthwhile, but we each have our own preferences for what we’d like to do and see. For me, it was hiking. I wanted to go out there and walk up some Swiss mountains and see some geology on the way! There were two perfect options for this. One of them involved visiting a big dam and then hiking for most of the day around that region. The second one involved a hike up a fairly tall mountain peak.

Hiking in the Swiss Alps – 2008

I believe the name of the place with the dam started with an L, so let’s just call that the L-dam. Then the mountain… all I remember is that there were cows and horses on the way, so I’ll go with cow-mountain.

The L-dam

The morning of our trip was fairly chilly and cloudy. We were all so tired in the morning. The late night partying combined with the early wake-up was a drag. Even now I can hear the organizers walking through camp in the morning, beating on metal pans and pots to wake everyone up. The horror…

My tired friends in the mornings, Switzerland 2008

I recall we took a fairly long bus trip to reach our destination. I also specifically remember the road was very winding with many sharp turns. This, because every time I tried to fall asleep the bus would turn and I’d end up banging my head against the window… concussion number 45.

Then finally, about two hours later, we arrived at the L-dam. The place must have been beautiful. Too bad we couldn’t see much due to the clouds. Ok, I’m exaggerating, but to be fair, it was pretty damn cloudy. At least for the first part of the day.

My friend Daniel in the clouds

We sat out on a trail following the lake. On the way, we had a few stops at several rock outcrops. I recall one of them had a bunch of nice garnets and, everyone took a piece with them. For the non-geologist readers, garnets are basically cool looking minerals that are sometimes used as gems. They kind of look like little mineral balls with nicely shaped geometric faces. Some of these garnets can even grow to a few centimeters wide. Take two of these big garnet balls and a long staurolite in the middle and you have a recipe for an obscene Bachelors dissertation project “wink, wink”.

The L-dam, somewhere in Switzerland

The weather started improving during the day and finally we got to see our beautiful surroundings. Gorgeous mountains on each side of the trail and the lake behind us. It was a wonderful field trip that I would gladly do again.

Hiking around the L-dam lake

Cow-mountain

On our second field trip in Switzerland we had the perfect hiking weather. Beautiful clear skies on a warm summer’s day, with just the right amount of a cool mountain breeze to keep us fresh.

The perfect weather and scenery for a lovely mountain hike

We started our hike from an already relatively high point and had to reach a peak of around 2500m. On the way we passed a bunch of horses and cows. For whatever reason this images stayed with me, hence why I decided to name it cow-mountain. Maybe it’s due to all the old “Milka” chocolate commercials with the cows and the Swiss Alps. Does anyone remember those?

Our EUGENeers gathering for some field geology

I recall our geologist professor/guide for the day had quite the hefty pace. So much so that some people had a hard time keeping up with him. I can’t remember what else we did during this field trip, except for walk, walk, walk, higher and higher.

Slippery terrain and impressive rock outcrops weathered by the elements

As you may imagine, the hike was absolutely worth it. The views we had on the way and especially from the top of the mountain were incredible. We even got to see some glimpses of snow here and there. Remnants of old glaciers, now just a thing of the past.

Me and Daniel: the brotherhood

Heading home

After the wonderful week in Switzerland we embarked on our multi-train journey back to Romania. All was going well, until we had to board the final train in Vienna. The second class cars were so packed that some of us had to upgrade to first class at extra cost to get on the train. When I mean packed, I don’t just mean all the seats were occupied, but that so many people were squatting on the train car hallways everywhere that there was simply no room.

It was an over night train ride too, so since I was very tired after the long week and the previous train rides, I agreed to be one of the guys to pay the 50 euros extra for the upgrade to an actual bed. That didn’t stop me and my volunteer friends from moping all night about the expensive ticket. However, we found a satisfactory solution. This first class premium service included a complementary 0.5 liter bottle of water. We simply told ourselves that it was that damned bottle of water that cost us the extra 50 euros.

Us and our 50 euro water bottles

In my next post I will jump ahead one year to EUGEN 2009, which was held in The Netherlands. So stay tuned for that!

EUGEN: Eu-What?

EUGEN: Eu-What?

Alright, so this week’s post is going to be a bit different – and yes I’m really trying to turn this into a weekly thing.

I will go further back in time to my first travel adventure out of Romania. Well, at least the first non-family related one. This all happened in 2008, during my second year at University. I know, feels like a lifetime ago… So one of my friends and classmates shows up one day talking about a summer camp he found out about. An opportunity for geologist students to go camping in Switzerland, relatively cheaply.

The organization doing this was called EUGEN. Which is a fairly common Romanian name and also happened to be the name of my uncle’s neighbor. Oh but it’s not that Eugen, it’s actually the European Geoscientists Students Network. I guess they left the S out of the acronym because EUGESN doesn’t roll off the tongue as nicely as EUGEN.

What is EUGEN about?

Back then I didn’t know anything about them, but as I would find out, they are a German-based organization that had been doing yearly summer camps for geologists and geology enthusiasts for a few years. Each year participants would hold a voting session where they would decide what country would host the next year’s EUGEN event. The whole thing would be fairly cheap and even cheaper for students living in the poorer eastern European countries. The event would last a week during which there would be various field trips one could choose from, social events, lectures and a cultural trip. Oh and a lot, and I mean A LOT of alcohol. All in all it’s an absolute blast of a week. A chance to visit another country, meet new people, make a bunch of friends and have a great time. The best part is that EUGEN continues to date! So what are you waiting for geologically inclined reader? Go! Fly off to Slovenia for a great time this summer!

EUGEN Austria in 2018 – Udra Udra!

Alright, so I went off on a bit of a tangent there, but I’m always happy to do some PR for these guys. Shout out to all my EUGEN readers out there!

Back to 2008 and when I first heard about them. This was back when I was piss-poor, so any cost was a high cost for me. Regardless, the opportunity was incredible and my parents were happy to sponsor my trip.

Off we go

It was some time during August, as it usually is, when the event was hosted. We had a fairly large group of Romanians attending that year. Most of which were university classmates of mine. I remember the logistics of getting to the location were quite tricky. Mostly because none of us had cars to drive. There were no easy flights either, so the only option we had really were trains. I think we had to change 4, or 5 different trains in total. I believe it was over a day’s worth of train travel.

The obelisk of Horea, Cloșca and Crișan in Alba Iulia, Romania 2008

The first train was from Alba Iulia, Romania to Vienna, Austria. The second one would cross Austria and take us to around Innsbruck, where I think we had to change to another train that would cross over the Swiss border. Then I know for sure there was at least one, if not two more train changes within Switzerland. This was mostly because the event location was near a tiny little village that nobody outside Switzerland has heard of called Domat/Ems. The village is close to a bigger town that nobody outside Switzerland has heard of called Chur. Chur is actually pronounced Coor, or Cur, like ass in Romanian. Sorry, I just had say that – Gaudenz, I hope you’re reading buddy!

A quick stop in Vienna, Austria – Mandatory taking of photos as proof that we went there in 2008

The experience

Now, I won’t go into day by day details of my excursion to Switzerland. Primarily because it’s been such a long time that I can only recall bits and pieces of it. However, I will reserve my next post to go over some of the wonderful places we saw during our field trips.

As for here, I would just like to state that it was a fantastic experience. Not just for myself, but for all of us from Romania that went to EUGEN 2008. The amazing field trips, the great people we met, the evening parties, the incredible food! Oh God, the Italian food night when everyone had like 3 portions and then the toilets couldn’t handle it anymore… The Italians serenading the chefs with live music… What a night! I remain extremely grateful for the organizing team and EUGEN for the opportunity.

Switzerland was/is such a radically different country then Romania that it’s like night and day. A real eye opener to how nice and civilized a country can be. Well, kind of like Norway for those who have read my Norway series. For those who haven’t, well what are you waiting for? It’s right here!

Walking around Chur, Switzerland 2008

Starting to feel like this post is one big advertisement, eh? Well, you bet your Chur it is!

Hope you’ll stick around for my next post about our Swiss EUGEN adventure! Until then, I bid you farewell.
