NPGallery Asset Detail

Paleogeographic maps of North America. Six maps show the changes in the location and configuration of North America over the past 260 million years ago. The following text is on the maps:
1. 280 million years ago (Permian period): Paleozoic orogenies culminated in the Appalachian Mountains and the formation of the supercontinent Pangaea.
2. 170 million years ago (Jurassic Period): Continued rifting since the Triassic opened the Atlantic Ocean and Gulf of Mexico basins and separated the continents.
3. 50 million years ago (Eocene Epoch): Continuous weathering and erosion wears away the mountains; Coastal Plain builds out.
4. 15 million years ago (Miocene Epoch): Gulf of Mexico deepens, continuously collecting heavy sediments; river patterns begin to emerge in southern Texas.
5. 15,000 years ago (Pleistocene Epoch): Glacial ice from continental ice sheets locks away vast quantities of water and global sea level is lower; rivers cut into coastal sediments.
6. Present day (Holocene Epoch): Fluctuating sea level l
