英语博客：Road works.

　　This Spring, we have experienced an unusual amount of rain, so much so that it has caused problems in many areas. I was driving to a local bakery the other day, when I came to some road works. I had to stop my car and wait for the heavy machinery¹ to get out of the way, so I took a few minutes to look around at what had happened. The road followed a hillside that was cut away to look a bit like a cliff, but the mixture of rock and soil looked crumbly. The consistent rain over the course of a week had loosened the rock from the soil and brought some boulders² down onto the road. A very dangerous situation! Watch out drivers! The heavy machinery was clearing the road so the traffic could continue. When I got home, I looked up the geology of this area on the internet. It turns out there are two trails that a person can drive along to view an enormous variety of geological activity. Apparently³, about 17,000 years ago there were enormous glaciers⁴ covering a lot of North America. It just so happens that there was a blockage⁵ of ice that stopped a huge lake of melted water from flowing south. When the ice block finally gave way, the gigantic flood affected⁶ this area by depositing massive 200 ton boulders in strange places, and tons of gravel⁷ in other places. Scientists say that there is evidence of 50 cubic miles of earth and rock being displaced up to a hundred times, and contributing to what is now this area. It's funny what you learn by looking something up on the internet, isn't it? A man who has written a book about the geology of this area, Mr. Charles L. Mason, writes that there has been "a buffet⁸ of geological events....that are unparalleled nearly anywhere else on earth." Gosh, and I learned all of that because I had to wait for some road works. Whatever will I learn next?
