The Proterozoic Grenville orogeny occurred around 1 billion years ago, and it marked the assembly of the supercontinent Rodinia. The Grenville orogeny resulted in the formation of the Grenville Mountains, which were located in the eastern part of North America. The uplift of the modern Rocky Mountains (A) and the ancestral Rocky Mountains (B) occurred much later during the Mesozoic era. The assembly of Pangaea (C) occurred during the late Paleozoic era, after the Grenville orogeny.
