Grimsey Island, Arctic Circle, and Husavik, 7/30/2021, National Geographic Explorer

After a night’s steaming from Isafjardardjup in the West Fjords, we woke to glassy seas and clear, sunny skies off Grimsey Island, 41 km north of the Iceland mainland. Grimsey is home to some 155 people and has the distinction of being cut by the Arctic Circle, marked by a monument. Its spherical shape allows the marker to be moved as the exact position of the Arctic Circle shifts through time.
Along our way to the marker, literally thousands of puffins hugged the sea cliffs we walked along. We then shifted positions and, after an early dinner, departed by bus for the spectacular waterfall known as Godafoss and Thyeistareykir, an impressive geothermal field that has been harnessed for electrical power generation.

We arrived in Saglek Fiord on a windy Labrador day, the dramatic high cliffs of the fiord bearing witness to the sheer power of the glacial ice that carved them. Late August weather in northern Labrador can be uncertain -- the bright sunny days sometimes give way to howling winds and driving rain. But our weather luck held as we were treated to dramatic changes in light and shadow on the multi-hued rocks. The majestic beauty aside, we came to Saglek intent on kayaking the protected waters of the inner fiord. But our wildlife luck from earlier in the trip also held and we saw bears almost everywhere National Geographic Explorer sailed. First, we spotted a mother polar bear and two young cubs scrambling over the rocks and climbing the hill with an adolescent bear following along behind. Before long, someone spotted a black bear and then another polar bear. And so it went, until it became apparent that kayaking in this location wouldn’t be on the agenda! Instead, we took to the Zodiacs. After spotting yet another black bear, we found two red Adirondack chairs marking the start of a trail at the head of the northern fiord. A mother polar bear and her cub snoozed in the sun nearby, almost as if they were waiting to welcome the next group of hikers. In all, we saw eight polar bears and four black bears in a single afternoon. In the absence of pack ice, bears were on the land and sometimes in the water. In the past it was uncommon to see black bears so far north, but they now seem abundant, drawn to the crow berries ripening in the sun on the slopes of the surrounding hills. Location really is everything, and the calm waters of the inner fiord gave way to gusty winds and whitecaps as we headed back to the ship to see what the chef had planned for the evening.
You may not know it, but you’ve probably seen the dramatic Vestmannaeyjar Islands off the south coast of Iceland before. It’s like sailing into an Instagram picture. The uniquely sculpted land is both picturesque and memorable. Heimaey is the most amazing. The harbor here was nearly sealed off by an enormous eruption in the late 1970s that demolished many of the houses in the town at the water’s edge. Today, we climbed the remaining lava pile, still warm from the magma lurking beneath the island’s surface. The blue sky gave us broad views, and the strong winds gave us a true taste of the local life. After dinner, we got a closer look at Surtsey—a volcanic island that is younger than many of us on board. It’s a bittersweet but fitting end to our explorations of the land of fire and ice.
After a late night yesterday at the Arctic Circle on Grimsey, we woke this morning to part sun, part cloud, gentle breezes, and calm seas. Since leaving Grimsey, we travelled to the northeast corner of Iceland and then to the south along Iceland’s east coast. Guests enjoyed a bit of a sleep-in this morning, a hearty breakfast, and presentations by Birna Imsland, our cultural specialist, on Icelandic Sweaters: Armor of the North , and Dana Johnston, our geology specialist, on Glaciers and Glacial Landforms . Our afternoon began with an on-board visit from the directors at Skalanes. They explained its rich archaeological record, documenting a subsistence lifestyle extending back over 1,000 years. While they spoke, the clouds dissipated, and we had perhaps the best weather we’ve ever enjoyed at this site. We split into two groups, one on shore visiting the archaeological sites, and the other Zodiac touring the geological wonders of the nearby cliffs. While both were immensely fulfilling, most agreed that geology ruled the day. Highlights included: magnificently exposed columnar basalts showing clear evidence of having been deformed by flow (photo A); igneous dikes, representing feeders for the overlying lava flows (photo B); brick-red baked layers, representing soil horizons overridden and baked by subsequent lava flows (photo C); a brilliant green area of hydrothermal alteration now consisting of bentonitic clays (photo D); and even an example of a basaltic dike cutting these brilliant green clays (photo E).
