Ontario Rocks: Three Billion Years of Environmental Change

In its long and rocky past, the place we call Ontario has traveled across the equator, been peppered and pockmarked by meteorites, seen the rise and decline of towering mountains, and gave rise to some very strange and now extinct organisms. In fact, what seems like a changeless landscape was once covered by vast seas and huge, continent-wide ice sheets which measured 2 kilometres thick, leaving in their wake, the Great Lakes.
