This mountain chain formed when a "baby" continent called the Grenville Province craton collided with the Superior Craton, which was the main core of the Canadian Shield. No one knows for sure how tall this mountain chain was, but most think it was at least as tall as the Rockies, and maybe as tall as the Himalayans. Other than these small peaks, the mountain chain has long since eroded away.Karen Brzyshttps://www.blogger.com/profile/07682821985791547514noreply@blogger.comtag:blogger.com,1999:blog-5978191009449322702.post-54077717438001298002012-05-15T21:09:59.158-04:002012-05-15T21:09:59.158-04:00Is that Canadian Shield I see?
