Winter satellite image, showing the ice cap and the main outlet glacier troughs. The Kaldalon valley runs towards the bottom left corner of the image. Note that the ice cap is asymmetrical -- the highest part is towards the eastern edge.
My old friend Dave Sugden has produced a little booklet based on his diary of the Oxford Icelandic Expedition 1960, which we jointly led and organized. (It was not exactly a gigantic undertaking. There were only 4 of us, but one has to start somewhere.......) We were in the field for a month, and the total cost was £360!! Anyway, very pleasant and nostalgic reading.
We worked hard while we were in the field, and our mapping (plane table and no theodolite) and observations led to our first ever publication, in the journal Geografiska Annaler. It was very descriptive and naive, but as I said, one has to start somewhere.......
I had forgotten the details of our trip onto the ice cap on 18 July 1960 -- our first experience of working with ropes and ice axes in crevassed terrain. We encountered no great hazards, but close to one of the summits on the ice cap we encountered a vast crevasse which we were not equipped to deal with. We were in thick cloud and working off compass bearings, with visibility around 20m. So then we had no option but to turn back. That was an 18-hour day, and we were all exhausted at the end of it.
