Geological History
Visitors from Space
Approximately 1.8 billion years ago, the relative peace of the Canadian shield was quite literally shattered by a 16km wide visitor from space. Where Sudbury exists now was ground zero for the impact which generated a 160km wide crater and ejected material kilometers into the sky.
The impact was so great that debris rained down in Thunderbay and around Lake Superior, as far west as 800km from the impact. The resulting fireball, air blast and tsunamis would have instantly changed the landscape for thousands of km around the impact. This wasn’t the last time we were visited from space.
