Now that we have the setting let us get to the "meat" of this blog post! In the area that is now the state of Iowa in North America a large asteroid struck the Earth. The impact was equivalent to 1,000,000 Hiroshima nuclear bombs, created earthquakes in excess of 10.0 magnitude, and generated tsunamis hundreds of feet high. The asteroid dug a mile into the Earth in a fraction of a second and formed a crater about 24 miles in diameter. “The impact is said to equal 10 trillion tons of TNT, resulting in an electromagnetic blast that incinerated anything within 130 miles and wiped out all life within 650 miles of the blast” (Pfeiffer). In fact scientists once believed that this asteroid impact may have been the culprit that wiped out the dinosaurs. Of course, we now know (at least we are pretty sure) that the asteroid that wiped out the dinosaurs struck 65 million years ago.
All of the limestone that was pulverized was able to mix with the groundwater deep underground and create the only natural soft water source in Iowa. Engineers want to tap into this massive area soft water under the ground and they believe the softest of the water is located in the center of the crater. Plans are being put together to drill into the center of the crater in hopes of creating a soft water well to supply Manson and neighboring Iowa towns with fresh water.
Hopefully engineers and scientists succeed and, in the process, gather more scientific evidence regarding the meteor and the massive impact it had on Cretaceous North America.
