Wooster Geologists

Mark Wilson June 27th, 2009

Today I took a day trip with about 25 other people on the small ship M.S. Polargirl in Isfjorden. The geology in view was fantastic, it didn’t rain, and the sun came out occasionally in the morning. I also got to answer numerous questions about geology from my fellow passengers, which I enjoyed. This little trip also gave me more information about the stratigraphy and interesting geological issues which future Wooster students may be able to address.

There are many abandoned mines along the shores of the fjords. Most are easy to spot because the mine developers wanted to be able to transfer their products directly to ships from the shore. Two types were visible on this trip: gypsum mines and coal mines.

Abandoned gypsum mine at Skansen. The gypsum and anhydrite units are visible as white units at the base of the mountain on the right. The mine is on the left almost completely covered by talus and snow. The mine was abandoned soon after it was started in the 1920s because there was more anhydrite than gypsum in the units.

This is the abandoned Russian coal-mining town of Pyramiden. We were unable to land there because of the thick pack ice between us and the harbor. The town was evacuated quickly in 1998 as it became evident it could not survive economically without the subsidies it had received from the Soviet Union. I wanted to see its "northernmost statue of Lenin".

The very steep mountainsides on the edge of the fjords have developed spectacular talus cones dropping down into the sea.

Talus cones along the margin of Tempelfjord. Two cones were modified by the glacier now confined to the adjacent fjord.

We also saw three glaciers nosing into their fjords. One is still calving off icebergs.

With the Nordenskiold Glacier in the background, along with pack ice, this is as far as I can tell the northernmost Wooster geologist on June 27, 2009 (at N78.64044°, E16.43892°). He certainly is the coldest Wooster geologist on this date.

Two short clips: the ship moving into pack ice outside Pyramiden, and waves lapping onto an iceberg in Isfjorden.

I’m between geological field trips right now. I left Russia by train through Karelia to Helsinki, Finland. It was a remarkable trip through woods and villages, with the swampy environs of St. Petersburg giving way to higher and drier ground where ribs of granite occasionally showed. Next week I go to Spitsbergen in the Arctic to look at a Jurassic sequence for a few days, and then I meet two Wooster students, Palmer Shonk and Rob McConnell, and an Ohio State University paleontologist, Bill Ausich, in Estonia where we will work in the Silurian with our Estonian colleague Olev Vinn.

Helsinki is, of course, a highly cultured city with many attractions. I don’t want to minimize those, but since this is a geology blog, we must note the gorgeous granite mounds which dot the city.

They were polished smooth on their upper surfaces by Pleistocene (and Holocene) glaciers, which left classic striations showing the direction of ice movement. The Finnish Parliament building is in the background.

Tomorrow I leave by train for the ancient city of Turku on the southwestern coast of Finland, and then the Aland Islands for a quick look. It’s a tough job, but someone has to do it.
