Studying Impact Craters
Here is some more information on a previously covered topic. Drilling is set to begin in September, on a crater located in the Chesapeake Bay. They are planning to drill over 7,000 feet into the Earth’s crust! I had no idea they were planning to take cores from that far down. â€œWeâ€™ll be crossing bridges that nobodyâ€™s crossed,â€ said USGS scientist David Powars, one of the first to suspect an impact crater lay under the Chesapeake Bay. Powars and other scientists, trying to figure out why some aquifers were salty and why older fossils could be found l ying on top of younger ones, announced the existence of the crater in 1994. For decades prior, such strange evidence had been considered the results of poor sampling and poorer science, rather than the ground truth of a cosmic collision. Here is the USGS web page on the project and more information as well.
