The geological context of Iceland is interesting – it’s the only place where a volcanic “Hot Spot” coincides with the Mid-Atlantic Ridge – Ricker et al (2013)
This is “The Table”, just south of Garibaldi Lake, BC. “Tuyas” are circular, flat-topped volcanic constructs found in many locations around the world, most notably in Iceland, Siberia, Antarctica, and BC. – Andre Charland
Mark’s thesis was about the formation of Tuyas. In a nutshell, they’e not all created equally…and it gets complicated in a hurry – Þórðarson (2008)
Base camp. This is about as remote as you can get
– M. Koleszar
The morning commute – M. Koleszar
Because of geography, the island of Heimaey always had a pretty good natural harbor. – M. Koleszar
Which was made even more sheltered by the volcanic eruption of 1973! – M. Koleszar
Iceland is pretty windy. This erosion was caused by pebbles swirling around in what eventually became a fairly substantial pit! – M. Koleszar
This is Seljalandsfoss waterfall…you can walk behind it! – M. Koleszar
Gullfoss (“Golden Falls”) was the site of a proposed hydrolectric project in the 1950s. It is now protected, and one of the most popular tourist attractions in Iceland. – M. Koleszar
Incredible – M. Koleszar
Iceland is otherworldly…and gorgeous – M. Koleszar
The”Krafla fires” lasted from 1975-1984 and represented a significant volcanic “extension event” – Sigurður Þórarinsson
This looks to be a pretty lonely ranch. The sheep might help. – M. Koleszar
This is the last landfal before reaching Antarctica…about 15,000 km further south – M. Koleszar
Resiliance – M. Koleszar
Resiliance #2 – M. Koleszar
Birding is popular in Iceland – T. Koleszar
Common Murres (Uria aalge) – T. Koleszar
Atlantic Puffins (Fratercula arctica) – M. Koleszar
American Oystercatchers (Haematopus palliatus) – U. Koleszar
Iceland Ponies – U. Koleszar
This is Grímsvötn (“Grim Waters”), which erupted beneath a glacier in May of 2011, disrupting air traffic throughout northern Europe. – Páll Stefánsson
Mark’s Powerpoint presentation described this as “The continental divide”.
He knows more that I.
For me…it’s just stunning. – M. Koleszar
Mark Koleszar – “Geological tales of Iceland” by Andrew Bryant, 17 Oct 2019.
Mark recently completed his Masters thesis at the University of Iceland, entitled “Flat-topped volcanic edifices in Vonarskarð, Central Iceland, and on the Kolbeinsey Ridge“. You can learn more about his research here, or read his full thesis here.
Geology is one thing. Iceland is something else.
Over the course of three years, Mark got to visit places that few humans have ever seen – indeed his principal field study areas are about as remote as it gets. Iceland is a place of wonder; waterfalls, volcanoes, ponies and puffins. And Mark (and family) are very talented photographers.
So I think it best to let the images speak for themselves.
