West Fjords, Iceland – We’re happy to report that the 2011 Iceland Keck crew has safely completed a productive field season. Nearly two weeks ago, a boat dropped us off in Hornstrandir, a nature preserve that encompasses most of the northern portion of the West Fjords. Our field area centered around Hrafnsfjordur, or Raven Fjord, in the southern extent of Hornstrandir. We had no idea that Hrafnsfjordur was a popular destination; it’s one of the primary drop-off and pick-up points for backpackers in the region. We must have seen at least half a dozen hikers during our stay. Hiking trails snake their way around the fjord and over the passes, which was fortunate for us since we had to access all of our field areas on foot.
After a couple of days of recon hiking as a group, the students selected their projects and went to work. Most students chose to map a portion of the fjord, although one student focused on mapping and sampling dikes. Students worked in teams of two, each team being assisted by a faculty member.
Field work was challenging. Like our Alaskan colleagues, we had dramatic stream crossings, treks across snow, and hikes up steep terrain. Although we never saw a bear, we spotted an arctic fox in the distance. Thankfully, the fox wasn’t interested in our food. Dehydrated meals at the end of a long field day never tasted so good!
The weather was mostly good, by Iceland standards. It seems as if we were constantly confronted with either bugs, wind, or rain, but always just one at a time. Whenever Emily worked in her area, though, the sun would shine!
We took a chartered boat back to Isafjordur on Wednesday and spent one last day in the field mapping a local mountain called Sauratindur. Now that we’re finished with field work and have returned to civilization, we realize how thankful we are for hot showers and soft mattresses. Still, there are some things that we’re already missing: the view from our tents, the sound of the waterfall (especially at night), the soft moss, our own private fjord, the hot cocoa, our special treat at the end of each day, and the freshness of the air.
Tomorrow, we start our long journey back to the states (via Reykjavik). We’re eager to get back to Wooster to start processing our samples. Hrafnsfjordur offered us an amazing amount of what we think are intermediate lava flows, which would be unique for Iceland. Dominated by basalt with local regions of rhyolite around central volcanoes, intermediate lavas are relatively sparse. Our field mapping, thin section observations, and geochemical analyses should yield some insights into the formation of Hrafnsfjordur’s central volcano. Stay tuned!
