The Geologic History of North Carolina
-
251 Mya: Triassic
North Carolina was still most likely a part of Pangea, near the equator. Appalachian Mountains were complete at this time. Approximately 620 mile long mountain range with North Carolina included. -
65.5 Mya: Palocene
The Coastal Plain of NC was underwater, but the ocean began to recede later in the Cretaceous Era eventually allowing the Outer-Coastal Plain to appear and be above sea level -
24.0 Mya: Miocene
Due to rapid erosion in the Piedmont area, became very uneven. Eventually forming the Uwharrie Mountains. -
5.3 Mya Pilocene
Due to the stabilizing climate the Blue Ridge and Piedmont area appeared as visible in NC today. A flourishing forest with fir, oak, and hickory. Most rivers and river basins were most likely formed during this era due to glaciers fully receding inland. -
1.8 Mya: Pleistocene
Sand Hills formed due to erosion carrying sediment to the "Coastal Plains." Eventually, heavy clay sinks downard causing sands that form dunes due to the wind. Most likely when the Fall Zone formed. Due to heavier rocks becoming more soft. Also, due to the glaciers receding a ridge was left above sea level, which was the Barrier Islands. -
9000 BCE Holocene: The Beginning
In approximately 9000 BCE, the massive glaciers and incredibly unstable climate has became stable enough to support human life. Thus, human life began. And people eventually came to North Carolina! -
