It is cool how scientists determent the sea stack took less than a million years. I think it used to be part of land and that is why there are remnants of a house on the top. I also agree that if archaeologists were to look for fossils they would find water creatures. Question, how come the different layers of rock are different colors (shades)?

When I first took a look at the picture of the gigantic sea stack I thought that it was photoshopped. It did not look real! Nature really is beautiful. I also thought that it must of took millions of years to form but it did not take that long. However, it did form millions of years ago.

Have you ever wondered how sea stacks form? Well, a recent sea stack was found that had not formed over millions of years; it had only formed in around 10,000 years. Usually, they form very slow. But, this one formed very fast. In fact, when they found it, it was still connected to mainland. A daredevil in 2016 climbed the immense cliff and made it to the top. That was the first time someone had set foot on the cliff since 1990! That is cool, right? But, there is more. scientists found the remains of a medieval house along with a broken quern stone. A quern stone is a stone used to grind corn. This helps me infer that the family living there grew lots of corn, and probably ate it on a daily basis. As you can see, this amazing sea stack is a natural wonder to behold.

I learned that the sedimentary layered rock formed during the Carboniferous period lasting 359,000,000 to 299,000,000 years ago which was before even the dinosaurs. If there does happen to be fossils from that period, then people would probably find things including coral, brachiopods, and crinoids according to McNamara. In 1393 an arch leading to the 150 feet sea stack was destroyed during a storm that may explain why it was named Dun Briste which is Gaelic for broken fort.

Scientists say that Dún Briste, the sea stack, was formed over tens to hundreds of thousands of years. It is a layered sedimentary rock formed during the Carboniferous. I think there may be fossils from that time, and that it would be interesting to find one and study it. The stack is 150 ft. tall. I think its weird that no one had set foot on it for 26 years, since 1990! I suspect people used to live there because of fragments of humanity.
