Sudbury Basin
46°36′N 81°11′W

 Sudbury basin, or Sudbury structure, is a huge impact structure in Ontario, Canada. It is the second largest confirmed impact crater, as well as one of the oldest.

The original crater is believed to have been a lot larger than the current 200km (120mi) diameter crater that is there today.

They believe that the bolide that created the crater was over 10km (6.2mi) in diameter, and struck the earth 1.849 billion years ago. The impact was so intense that it scattered debris over a 1,600,000km2 area around the point of impact. Rock fragments from the impact have been found in Minnesota, over 800km (497mi) away.
