Back then Missouri was covered in a shallow sea. When the meteorite struck it created a crater that was 12 miles wide and jettisoned rocks and debris over a much larger area. Geologist combing the area have found evidence of this impact and are continuing to put together the pieces to make their case. The impact site is located north of Coon Creek and just south of the Village of Vista, Missouri to the west of Highway 13.

It seems that when the meteorite struck it broke up gravel sized bits of shale that in the soup of silt and minerals that remained after the impact eventually conglomerated to make these round rocks.
There are many geologic wonders of Missouri left to be rediscovered by you. Get out and see what you can see of this wild Missouri.
