Iceland north coast. Wild beauty everywhere you lo Iceland north coast. Wild beauty everywhere you look. While most of Iceland is covered in volcanic basalt, Tjörnes peninsula features a rare, 1,200-metre-thick sedimentary sequence which we went to have a look at. These strata act as a timeline, tracking global climate shifts, ancient forests, and changing ocean currents. The Bering Strait Connection: For millions of years, the Atlantic and Pacific Oceans were completely separated. When the Bering Strait broke open in the N Pacific, Pacific marine life flooded into the Arctic and travelled all the way to the North Atlantic and here to Iceland. Scientists have tracked this exact moment in the cliffside strata of Tjörnes, where Pacific bivalve (mollusc) fossils suddenly appear alongside Atlantic species. Recent radioisotope dating of these beds places this biological migration event at roughly 5.2 to 4.9 million years ago, thus dating the original opening of Bering Strait. How awesome is that!

The Mamaku Tors and conical mounds just west of L The Mamaku Tors and conical mounds just west of Lake Rotorua. These features are the eroded remnants of a very thick (volcanic) ignimbrite layer that was erupted 240,000 years ago, resulting in the caldera now occupied by Lake Rotorua. The puzzle is that there is no evidence that the rock was eroded by a river or glacier. So what was it that removed all that material and where did it go? And why are the remaining stumps so similar in dimensions, and distributed across a wide area many kilometres across?
Lake Rotorua (top left on Google Earth image) is a Lake Rotorua (top left on Google Earth image) is a caldera (collapse crater) from a massive super eruption about 240,000 years ago. It has a relatively simple, not quite circular shape about 10km across. Just to the East is another, much messier caldera atleast twice the size and about twice as old. Its original outline had been obscured due to the eruption of multiple later craters and lava domes so that now there are many separate lakes scattered within it. This is the Okataina caldera, and the photo of Bruce Hayward shows the caldera rim in the background across Lake Rotoiti. We explored these lakes for another Out There Learning video to be produced some time in the coming weeks 🙂
